 This was not the first time Gavin MacLeod (qv) was involved with a  movie about Andy titled Sheriff Without A Gun. In TV or not TV  (Season 5, Episode 23) he was part of a phony film crew that showed  up in Mayberry to make the movie, but they turned out to be a gang  of bank robbers. This time hes a legitimate actor, playing the part  of Andy in the movie.
