Believe so, can't remember what he plays though.
Charlie chaplin's The Dictator.
I think. He basically plays a two part role as a Jew barber and Emperor "Hynkle" in parodied national socialist Germany.
Spoiler, highlight:
In the end, because the jew barber and Hynkle look exactly alike, the Jew barber gets up in front of the crowd and gives the speech while Hynkle gets jailed.
