When it comes to summer movies, looks can be deceiving. Take "21 Jump Street." The initial trailers made the 2012 Channing Tatum-Jonah Hill comedy look like another TV-to-film dog. But to our surprise it was good -- very, very good; an uproarious reboot.
Here are five other summer film comedies that vastly exceeded expectations:
"Caddyshack": Bill Murray chasing after a destructive gopher at an exclusive golf club. Rodney Dangerfield dropping one put-down after another, after another. A peppy Kenny Loggins song that burrows like a tick into your subconscious. Director Harold Ramis took these disparate parts and pieced together a 1980 classic that remains as evergreen as AstroTurf.
"Tropic Thunder": The inspired opening segment is enough to recommend this rambunctious 2008 mood booster about a film crew becoming involved in actual combat. The biggest surprise? A nearly indistinguishable Tom Cruise doing some bizarre dance moves.
"The Hangover": The premise of this 2009 flick is as tired as an Adam Sandler comedy; a bachelor party in Las Vegas spins wildly out of control. Yawn. But Todd Phillips' first entry in his bad-boy trilogy (the ensuing two chapters were atrocious) defied the odds with an escalating punch-drunk series of hilarious events and a game cast that included Zach Galifianakis, Bradley Cooper, Mike Tyson, even a tiger.
"Ted": Seth MacFarlane tends to ramble on, and this potty-mouthed teddy bear movie proves that. But even though some jokes go splat, there are moments that will have you laughing uncontrollably. And, oddly enough, this bit of 2012 rudeness co-starring Mark Wahlberg and Mila Kunis is sometimes heartwarming.
"This is the End": It was outfitted with one of the most unpromising concepts ever: A group of actors -- all playing themselves -- hole themselves up in James Franco's enormous house after the apocalypse hits self-absorbed Los Angeles. How in the world could this thing go right? Somehow, some way, this rude 2013 comedy from Seth Rogen and Evan Goldberg turned out to be comedic genius.
