Doctor Who episode 378: Planet of the Spiders – Part Three (18/5/1974)
I’m quite sold on Lupton: he’s easily the pettiest and most human villain the show has had in years (probably since The Highlanders). He gives a potted history of his backstory and it’s like he’s a character in a soap: embittered ex-sales wunderkind, forced out in a merger and now driven entirely on a quest to make other people as humiliated as he feels. This leads to an astonishing sequence in which he turns his spider’s mental torture back on her, forcing her to beg him to stop. This is the kind of person he is: he’ll torment a spider to make himself feel like the big man.
