Why Russians Are Revolting (1970)

This inept "comedy" has Sullivan (who also served as producer, director, and writer) playing a W.C. Fields type, complete with the great comic's accent (badly imitated). Sporting a Fieldsian character name, Cyrus Barnwhistle Diner, Sullivan goes back in time to pre-revolutionary Russia. There he encounters various historical figures from Lenin, Trotsky, and Stalin to Adolf Hitler. It's hard to tell which is worse, Sullivan's acting or his behind-the-camera work. Some footage from the 1920 silent film DR. JEKYLL AND MR. HYDE is tossed in with little effect.
