Can anyone name any other films/tv shows where any of the cast of IAMMMMW appeared together in even if they did not share any scenes?
I can't believe nobody here (myself included) has mentioned Sid Caesar and Carl Reiner in "Your Show of Shows". It's a bit before my time, but it's always cited as a part of the 'golden age of television', had the likes of Mel Brooks and Woody Allen as writers, and virtually invented tv sketch comedy. This skit features an utterly mad performance by ensemble member Howard Morris, who really should have been in this movie!

Wake Me When it's Over (1960) - starred Dick Shawn and Ernie Kovacs (unfortunately not in IAMMMMW), featuring Marvin Kaplan and Don Knotts.
shareAnother one that I've seen is "Where Were You When the Lights Went Out?" (1968). Terry-Thomas, Jim Backus and Ben Blue appeared in that one.
