3rd September 1940: birth of Pauline Collins, who memorably played companion-that-never-was Samantha Briggs in The Faceless Ones (1967) and Queen Victoria in Tooth and Claw (2006).
3rd September 1977: broadcast of first episode of Horror of Fang Rock, starting Season 15. The Doctor and Leela land at the lighthouse of Fang rock, where the two keepers, Reuben and Vince, are behaving oddly (indeed, Reuben so oddly that he is dead). And a ship is wrecked on the Rock…
3rd September 1993 – broadcast of second episode of The Paradise of Death. The Doctor rather bizarrely recovers from his fall because he is able to turn his whole body to jelly. The bad guys capture Sarah Jane Smith and take her to the planet Parakon, while the Doctor, Jeremy and the Brigadier set off in pursuit but land insyead on the planet Blestinu.
3rd September 2007 [?] – events of Revenge of the Slitheen (SJA 2008), where the slimy green gits attempt to infiltrate Park Vale Comprehensive School, attended by Luke (and Clyde, and Maria) but are foiled by our young heroes and Sarah Jane Smith.
Excellent find. Looking forward to the Aldbourne reports. (I’ve read that one later Countdown or TV Action Dr Who strip used images from that Aldbourne visit as photographic reference, complete with Countdown editor/Polystyle editorial director Dennis Hooper, I think being attacked by a paralysing ray.)
The first Tom Baker strip in TV Comic had similarities to The Seeds of Doom too – evidently no one was looking after the plants at the Polystyle office.
ETA: I think that Countdown the comic strip was not an adaptation, but original material; Polystyle always liked to include non-derivative material in their television-led comics, presumably for budget reasons.
