Jonah Hill and Channing Tatum in 21 Jump Street21 JUMP STREET

As an undercover police officer who, in 21 Jump Street, can say to his platonic partner "I cherish you, man" in a way that's both hysterical and intensely touching, Jonah Hill possesses a rare gift for completely unembarrassed sincerity. By now, it should go without saying that Hill is a sensational verbal comedian and a fearless physical one. But as in his bro-mantic scenes opposite Michael Cera in Superbad, the actor brings to this action comedy something few others would think to: absolute honesty and emotional transparency. Hill is funny as hell here, but his character is never a joke.

Anne Hathaway and Jake Gyllenhaal in Love & Other DrugsLOVE & OTHER DRUGS

In my 2009 review of the director's turgid World War II drama Defiance, I opened by asking, "Am I the only person who wishes that Edward Zwick would go back to making sharp, bitchy comedies like his 1986 Rob Lowe-Demi Moore romance About Last Night ... ?" Well, less than two years later, Zwick has returned to those romantic-comedy roots with Love & Other Drugs. Because, apparently, I needed another reminder to be careful what I wish for.
