Here’s a brief extract of a Tom Baker interview, in which he talks about his approach to playing the Doctor, as well as the plans for the 1970′s film ‘Doctor Who Meets Scratchman’, for which he co-wrote the script with Ian Marter, but which was never made.
“I never consciously thought it out. I never knew where I was going with ‘Doctor Who’, because the very essence of the character is that the Doctor never does know where he’s going. What I worked hard at was maintaining the spontaneity and ideas, keeping the audience surprised, since, after all, the Doctor was meant to be an alien. He wasn’t emotionally involved, except in the most heroic way.
“The script for ‘Doctor Who Meets Scratchman’ was about scarecrows becoming animated when a fertilizer on Earth goes horribly wrong. The scarecrows were able to make other scarecrows and they go on the rampage, raiding stores and using their sticks as weapons. The Cybermen came into it, too; there were wonderful scenes of the Cybermen coming out of the sea.
“The whole thing hinged on the fact that somewhere out in space was this creature called Scratchman, which is an old-world named for the Devil. He just wanted to make trouble. I remember the ending: we were going to turn the whole studio into a giant pinball table. The Doctor and his companions were stuck on this table and Scratchman was firing these balls at us. The balls disappeared down holes which were sort of gateways into other hells. It was a very violent film, but very funny too. The production office saw it and hated it, but I thought it was marvellous.”
