 Who drummer Keith Moon (I) (qv), who stayed with the Pythons in  the Caribbean as they wrote the film, was originally slated to play  one of the street prophets in the scene where Brian poses as a  prophet to hide from the centurions. Eric Idle (qv) saw Moon the  night of his death, and remembers him expressing excitement about  the role, which eventually went to Terry Gilliam (qv).
