Dumb and Dumber
The third of the actor's 1994 movies, Carrey teamed up with Jeff Daniels to play hapless pals Lloyd and Harry. The pair make a cross country trip to return a briefcase of money thinking it was left by mistake - only to later discover it was ransom money. The comedy has earned a cult following since its release and spawned a television series, a prequel and a sequel, but the stars only appeared in the latter.
