Shelved for two years before its limited theatrical release, Waking Up in Reno is the kind of comedy that makes you feel guilty for laughing. The lowbrow fun begins when Arkansas car dealer Lonnie Earl (Billy Bob Thornton, perfectly cast) cheats on his wife Darlene (Natasha Richardson) with Candy (Charlize Theron), the wife of his best friend Roy (Patrick Swayze). When the couples pack up Lonnie Earl's ill-fated SUV to see the monster-truck jam in Reno, Nevada, Roy's meager sperm count and Candy's surprise pregnancy result in a series of marital repercussions. Stuck in a no-man's-land between road-trip farce and redneck parody, this comedic misfire trades in dimwit stereotypes and white-trash condescension, showing its age with a thankless hot-Latina cameo by Penélope Cruz. It's painless enough to be watchable, and Thornton's character is a likeable fool as he surveys the damage he's caused. Watch carefully, and you'll find plenty of mostly unfulfilled promise along with a half-hearted chuckle or two. --Jeff Shannon
