The Mummy is probably my favorite "popcorn" movie. And highly quotable. And Brendan Fraser.
There's a...theory? Addage?...that comedic actors make better dramatic actors than vice-versa. Comedy is allll about timing. Just think about these actors:
Robin Williams - wins Oscar for Good Will Hunting, has acclaimed roles in The Fisher King, Dead Poets' Society, What Dreams May Come. Haven't seen the movie, but I've read/heard that he's REALLY creepy in One Hour Photo.
Bryan Cranston - We get to know him as the dad in Malcolm in the Middle, but he wins four leading actor in a drama Emmys for Breaking Bad (deservedly so), and he won a Tony for portraying LBJ on Broadway. Actually, he's won two Tonys. (We can also have a discussion about hits/misses of screen actors switching to stage)
There's a whole slew of other examples, but I'm not going to list them all.
