Tony Curtis

Tony Curtis in Some Like It Hot. He played Josephine to Jack Lemon's Geraldine, which later turns to Daphne. Confused? Everybody in this fill seems to be. Everybody seems to be playing someone else. A great old fashioned comedy.
Alec Guinness

In 1949 Alec Guinness got to die eight times in this film when he played generations of the same family.
Dustin Hoffman

Dustin Hoffman played Tootsie in the film of the same name. A very convincing performance and sometimes very funny too.
Eddie Murphy

Eddie Murphy as Ms. Klump, in The Nutty Professor. Convincing but also funny.
Patrick Swayze

In To Wong Fu, Thanks For Everything! Julie Newmar, Patrick Swayze really looks the part as Vida Boheme the dancing queen.
Robin Williams

Robin Williams plays Nanny McFee in Mrs Doubtfire. He seems to really enough the comedy of the role and plays a very convincing part.
