If there's been a zombie apocalypse and you're road-tripping alone though the wasteland, you could do worse than run into Tallahassee (Woody Harrelson), a bourbon-swilling bad-boy butt-kicker with a really cool car. This is where the careful hero of Zombieland, a kid nicknamed Columbus (Jesse Eisenberg), finds himself early in the film, and you can hardly blame him for hitching a ride with this swaggering Alpha Male. Still, they have their hands full not only with gibbering zombies but also with two sisters (Emma Stone and Abigail Breslin) who will stop at nothing to reach a Disneyland-like amusement park in L.A. Although Zombieland gets off to a rocky start with Columbus's overly-cute narration (he's got a list of rules for surviving in the zombie world), it settles into an amusing comedy, regularly interrupted by bouts of blood-letting. The road-trip stuff is enough fun that when the movie does arrive at its version of Disneyland, the air goes out of it a little; sure, there's a giant zombie blowout, with entrails flying, but it's not quite the same. Director Ruben Fleischer keeps the gags coming, although the movie is often funnier in its odd little asides (both Eisenberg and Harrelson are expert at this) than in its official jokes. Comic high point: an interlude at the home of a very famous movie star, who plays himself--and we'll leave the spoiler unspoiled, in case anybody hasn't heard about this funny extended cameo. --Robert Horton
