1. "The Doctor discovers that
Global Chemicals is more sinister
than it seems -
Copy !req
2. "and Jo discovers the strange secret
of the coal mine."
Copy !req
3. This episode was first shown
on 26 May 1973
and was watched by 7.2 million people.
Copy !req
4. This was a drop of two million viewers
from the opening episode
the previous week,
Copy !req
5. A number of shots in this story
used a process
called Colour Separation Overlay (CSO),
Copy !req
6. where the action was performed
against a backdrop of a solid colour.
Copy !req
7. The background could then be
electronically replaced
with a different image.
Copy !req
8. In this case, a solid yellow backdrop
was hung behind the lift cage set,
Copy !req
9. Glycerine was applied to the actors'
faces, to indicate their exertion
in stopping the falling cage.
Copy !req
10. As we cut back to the lift,
notice that Jo
seems to have lost her helmet...
Copy !req
11. For some reason,
the stated depth of the mine shaft
changes from 500 to 600 yards.
Copy !req
12. At the real Ogilvie Colliery,
the North shaft was 483 yards deep
whilst the South shaft was 546 yards.
Copy !req
13. As the unconscious Jo awakens,
her helmet seems to have
magically crept back onto her head!
Copy !req
14. The lamp returns!
Copy !req
15. The sound effect played in at this point
was specified
as a "screwdriver from 20 feet".
Copy !req
16. recorded on Monday 2
and Tuesday 3 April 1973 in Studio 3
at the BBC Television Centre in London.
Copy !req
17. On the other side of the studio
were the sets for the Engine Room
and the Pit Head Office
Copy !req
18. as well as Stevens's Office
and a small part of Cliff's Laboratory.
Copy !req
19. The script indicates that,
as the Doctor forcibly
slows down the winding gear,
Copy !req
20. parts of the surrounding mechanism
also collapse under the strain.
Copy !req
21. Poor Dai Evans was given a scripted line
at this point to show how unwell he is.
Copy !req
22. It simply reads, "Moan, moan"!
Copy !req
23. Dai is played
by Edward Mostyn Evans (1923-90).
Copy !req
24. A few months later,
he played the Exxilion High Priest
in 'Death to the Daleks' (1974)
Copy !req
25. And he was also considered
for the role of Ernie the poacher
in 'Pyramids of Mars' (1975).
Copy !req
26. As scripted, when the call ends
prematurely, Elgin turns to see Stevens,
who has cut the connection.
Copy !req
27. For that reason, the BBC requires
any fictional names to undergo
a process called Negative Checking.
Copy !req
28. This attempts to ensure
that any invented names of characters
or organisations that feature in a story
Copy !req
29. don't correspond too closely
with names in the real world,
thereby risking prosecution for libel.
Copy !req
30. This scene introduces
a new character to the story,
the company's chief scientist.
Copy !req
31. Originally, he was named Bell,
Copy !req
32. but the negative check performed
in late February 1973
returned a "positive" result:
Copy !req
33. There was a Douglas Bell working
as a scientist and chief executive
at the chemical company, ICI.
Copy !req
34. It was left up to the production office
to decide whether or not
they should risk using the name Stevens.
Copy !req
35. It was pointed out that there
was someone by the name of Stevens
employed in the chemical industry:
Copy !req
36. Frank Stevens headed up
the Sheppey Glue and Chemical Works
at Queenborough in Kent.
Copy !req
37. There was also
Professor Thomas Stevens (1900-2000)
Of the University of Sheffield.
Copy !req
38. He was an organic chemist
who co-discovered
the Bamford-Stevens Reaction in 1952.
Copy !req
39. We'll find out in the next episode
where the name Stevens really came from...
Copy !req
40. This scene was truncated during editing,
losing the opening dialogue
between Stevens and the Brigadier.
Copy !req
41. "Mr Fell? May I have a word?"
And the reply comes back,
"At once, Mr Stevens."
Copy !req
42. "Ralph Fell is our chief scientific
and technical officer,"
explains Stevens.
Copy !req
43. "An excellent fellow - if a trifle
over-scrupulous in his work -
an idealist, you know?
Copy !req
44. A small change to the scripted dialogue
occurs at this point.
Copy !req
45. In the script, Stevens says
that Professor Jones
"tried to borrow ours some weeks ago",
Copy !req
46. but this is altered in the recorded
scene to
"They tried to borrow ours yesterday."
Copy !req
47. The amendment helps to emphasise
the fact that Stevens
is being deceitful.
Copy !req
48. and as the entirely comprehensible
lunar operative Sam Becket
in 'The Moonbase' (1967)
Copy !req
49. The call-signs of "Greyhound" and "Trap"
Were established in the 1971 series.
Copy !req
50. A large chunk of scripted dialogue
from this scene
was excised prior to recording.
Copy !req
51. Notice Dave's pronunciation
of Llanfairfach here.
Copy !req
52. He's the only one who says it correctly.
Everyone else wrongly puts
a heavier emphasis on the "fair".
Copy !req
53. Dave asks to speak to Ron Owen
and, as he waits, Cliff asks
if there's any other way into the mine.
Copy !req
54. Here, Bert is talking
about the accident he mentioned
in the earlier deleted dialogue.
Copy !req
55. A rather neat little segue
between this scene and the next
was abandoned at this point.
Copy !req
56. As Bert sketches, the picture was to mix
to the official map of the mine
in the engine room.
Copy !req
57. You can just see it on the wall
behind Dave and Professor Jones.
Copy !req
58. Dave's reply about the West Seam
is slightly obscured and shortened
at the start of this scene.
Copy !req
59. Some small dialogue changes were made
in the upcoming conversation.
Copy !req
60. After the Doctor's line,
"For the age that you live in,"
his scripted line continues,
Copy !req
61. "I haven't seen anything like it
since a fellow I met
in Vladivostok in 2179..."
Copy !req
62. The Brigadier cuts across him:
"Doctor! Please! Miss Grant..."
Copy !req
63. Hang on a minute! United Chemicals?
Who are they?
We'll answer that one shortly.
Copy !req
64. The calendar in the guard hut shows
a 29-day month, indicating
that it's a February in a leap year.
Copy !req
65. Around the time of 'The Green Death',
the leap years were 1972, 1976 and 1980.
Copy !req
66. You can make up your own mind
in which of those years
the story is set!
Copy !req
67. However, to make the scene
a little more visually exciting,
Copy !req
68. In the strip, the Doctor and Sarah-Jane
get into the mysterious Vegpro factory
via an overhanging tree,
Copy !req
69. but make a hasty exit using
the raised platform of a fork lift truck
taken from the company's loading bay.
Copy !req
70. So why, in that deleted dialogue,
did the Brigadier name the company
"United", rather than Global, Chemicals?
Copy !req
71. It was because the nomenclature
went through several changes
during the scripting process.
Copy !req
72. The company was originally
called Universal Chemicals,
before becoming United Chemicals.
Copy !req
73. But this was too close to the name
of an existing company,
so it was changed to Global Chemicals.
Copy !req
74. Both of these are also occasionally
abbreviated in the script
as "U.C." and "G.C."
Copy !req
75. When Malcolm Hulke came
to write his 1975 novelisation
of 'The Green Death' for Target Books,
Copy !req
76. the company name was once again changed,
this time to Panorama Chemicals.
Copy !req
77. Even the final on-screen choice
of Global Chemicals
was not entirely without its problems.
Copy !req
78. Two days after the story concluded
on television, the BBC
was contacted by the sales manager
Copy !req
79. They had noticed what they took to be
"amusing comparisons"
between Gamlen and Global Chemicals.
Copy !req
80. In particular, their own "G" logo
was almost identical
to that used in the story.
Copy !req
81. This, they claimed, had caused them
"some slight embarrassment".
Copy !req
82. Two days later, the BBC wrote back.
Copy !req
83. "As you are no doubt aware,
the Dr Who series
does not attempt to portray reality.
Copy !req
84. "visits to other worlds,
battles with Daleks
and other monsters etc.
Copy !req
85. "Anyone watching the programme
would realise that any organisation
depicted was part of this fantasy
Copy !req
86. "and did not relate
in any way to reality."
Copy !req
87. They also disputed
the claimed similarity
between the two company logos.
Copy !req
88. The location chosen to represent
the exterior of the Global Chemicals
Copy !req
89. was the RCA International plant
on Intermediate Road in Brynmawr.
Copy !req
90. and the new owners wouldn't move in
until the late summer of that year.
Copy !req
91. For several years, the site was owned
by the computer firm Anacomp Magnetics.
Copy !req
92. It was completely demolished
in the latter part of 2008.
Copy !req
93. This whole sequence of the Doctor
breaking in, fighting the guard
and being captured
Copy !req
94. was filmed on Monday 19 March 1973,
the second of the three days
spent at RCA International.
Copy !req
95. After this sequence,
and before the Brigadier and Dave
arrive back at the mine,
Copy !req
96. "Below the main sheave wheel,"
observes Cliff.
Copy !req
97. "That's it," confirms the Doctor.
"Then our new cable runs to our
donkey engine which is here."
Copy !req
98. "So, all we have to do is cut
the original cable
and we're laughing," replies Cliff.
Copy !req
99. The Doctor smiles somewhat ruefully
at him and replies, "I never felt
less like laughing in my whole life."
Copy !req
100. In the script, the Doctor says here,
"Jo and the others may desperately
need my help."
Copy !req
101. So, where did the idea
for 'The Green Death' originate?
Copy !req
102. Writing for the publication
An Adventure in Space and Time in 1987,
producer Barry Letts explained:
Copy !req
103. "I used to take a magazine
called The Ecologist, which brought out
Copy !req
104. "Not only are we fast
using up irreplaceable resources,
such as fossil fuels,
Copy !req
105. "but we are also poisoning ourselves
with the resultant pollution."
Copy !req
106. The issue of The Ecologist in question
was published in January 1972.
Copy !req
107. It was co-authored by Edward Goldsmith,
the magazine's founding editor
and publisher, and Robert Allen.
Copy !req
108. The press reacted with horrified concern
to the publication
of A Blueprint for Survival.
Copy !req
109. The report was supported
by 34 distinguished biologists,
ecologists, doctors and economists,
Copy !req
110. but a few days after the magazine
was published, 187 scientists
signed a letter to The Times
Copy !req
111. A Blueprint for Survival had
a profound effect upon Barry Letts.
Copy !req
112. "I was so shaken by its arguments
that I remember saying to Terrance Dicks
Copy !req
113. "that I wished I worked
in an area of television
where I could do something about it.
Copy !req
114. Letts suggested bringing
in writer Robert Sloman
to work on the new story.
Copy !req
115. The reason for this choice
was two-fold.
Copy !req
116. He was credited on screen
for three of his four contributions,
Copy !req
117. but the first went out
under the pseudonym "Guy Leopold",
Copy !req
118. All this concealed the involvement
of his regular collaborator,
Copy !req
119. who was, unbeknownst
to the BBC management,
none other than Barry Letts himself.
Copy !req
120. "There was no BBC rule against producers
writing for their own shows,"
recalled Barry Letts in 2009,
Copy !req
121. "He lived five minutes' walk away,
so we'd get together
on a regular basis and discuss,
Copy !req
122. "Making sure first that Terrance,
as script editor, was happy with it,
Copy !req
123. "He'd then give it to me, a slow writer,
saying, 'Here it is,
do what you like with it.'
Copy !req
124. "I would then go through it,
keeping Bob's stuff
whenever I could see that it worked;
Copy !req
125. "At least fifty per cent
of the dialogue was mine.
Copy !req
126. That said, the environmental story
that Sloman and Letts
originally came up with
Copy !req
127. had nothing to do with coal mines,
oil refineries, toxic slime
or giant maggots.
Copy !req
128. We'll take a look at their
original plans
as we go through the next episode.
Copy !req
129. Dave's Welsh calls as they
search the mine were all ad libbed.
Copy !req
130. At this point he was scripted to ask,
"Bert, can you hear me?"
Copy !req
131. a brand of heavy-duty dark-green,
gelatinous hand cleaner
often used in the engineering industry.
Copy !req
132. So, if you suffer from scoleciphobia,
an irrational fear of worms and maggots,
Copy !req
133. then 'The Green Death' is probably
not going to be the story for you!
Copy !req
134. The tunnel collapse
that you see at this point
is not mentioned in the camera script.
Copy !req
135. The stage direction simply indicates,
"They begin to go back down the shaft.
Copy !req
136. "Worse still, three maggots
also wriggle out.
Jo and Doctor Who are trapped."
Copy !req
137. Notice something a little odd
about the closing credits?
Copy !req
138. The image in the background
is being played upside down
and in reverse.
Copy !req
139. Also appearing in this episode were:
Copy !req
140. Geoffrey Morgan,
Michael Cunningham
Copy !req
141. Billy Horrigan,
Alan Chuntz
as quick as I can.
Copy !req
142. Is that a light?
Where?
Copy !req
143. Up ahead. There.
Copy !req
144. Bert!
Copy !req
145. Here are we!
Copy !req
146. The light's green.
Copy !req
147. Put our lights out, then, Doctor.
Copy !req
148. Come on.
Copy !req
149. What an extraordinary smell.
Copy !req
150. Come on.
Copy !req
151. What is this stuff?
Copy !req
152. No, don't touch it.
Copy !req
153. Come on. Let's get on.
Copy !req
154. - Here's Bert!
Where?
Copy !req
155. Bert? Bert?
Copy !req
156. - Here you are, here you are.
Copy !req
157. Look at his hand.
- Oh!
Copy !req
158. It burns, burns.
Copy !req
159. - Where's the girl?
Gone on ahead.
Copy !req
160. Take him up to the surface,
quickly as you can.
Copy !req
161. - Let the professor take a look at him.
- What about you?
Copy !req
162. I'm going on ahead to look for Jo.
Copy !req
163. Tell the brigadier that I'll find her
and bring her back,
Copy !req
164. but don't let anybody
come down looking after us.
Copy !req
165. - You understand?
- Yes, Doctor.
Copy !req
166. It's far too dangerous.
Copy !req
167. Jo! Jo, are you there?
Copy !req
168. JO: Doctor! Here! Quickly!
Copy !req
169. - Doctor! Doctor, it's horrible!
- What is it?
Copy !req
170. Good grief!
Copy !req
171. Come on!
Copy !req
