Dallas Cavell in a very unusual move was brought in just to play dead in this episode, the standard BBC practice would be to either pre record the scene or use a body double combined with a photograph taken the previous recording session to avoid the actor having come in, he would have been paid regardless of the method.
Sergeant Benton's role in this story was originally filled by a new sergeant named West.
