The Hangover (Warner Bros.): Director Todd Philips ("Road Trip," "Old School") has for years been a specialist in rambunctious frat-house hijinks. Set in Las Vegas, his latest comedy will not disappoint his fans. With two days left before his wedding, Doug (Justin Bartha) and his groomsmen (Bradley Cooper, Ed Helms, and Zach Galifianakis) go on a bachelor-party blowout. The only problem is that, when the morning comes, the men notice that the groom is missing. With the clock ticking away, his friends have to trace back their actions and locate Doug, a wacky adventure that gets them in trouble with casino bosses, a mysterious baby, and a certain former world heavyweight champion. The movie won't win any awards for good taste, but it has plenty of hearty laughs.
