Come [The Android Invasion], of course, and John [Levene] not only had to play himself and an android version of Benton - he also had to shoot the Doctor. Barry [Letts] was so relaxed about this scene it quite threw John.
‘There’s no dialogue, just say what comes naturally,’ Barry said.
This absolutely froze John into total traction. Ad-libbing? That was for other people, not him. So he came over to me and said, 'Lis, what am I going to do?’

'OK, OK,’ he said. 'I’ve got it.’
So we began rehearsal then went for action. As per the script, Tom [Baker] got shot. John looked at his gun and said, 'Shit, I’ve shot the Doctor!’
