Take a look at Jim Carrey’s resume: stupid comedy after stupid comedy (“Ace Ventura,” “Dumb & Dumber,” “Bruce Almighty,” etc.), punctuated by terrific dramatic performances (“The Truman Show,” “Eternal Sunshine of the Spotless Mind”). He’s a great comic actor with surprisingly effective serious leanings. At this point in his career, you really can’t be sure about what you’re gonna get from him.
