Based on Steven Gould's sci-fi novels for teens, this big-budget adventure asks: what would you do if you could "jump" anywhere in the world in the blink of an eye? Reluctant hero David (Hayden Christensen) decides to rob banks and go sightseeing. The problem is - illegalities aside, of course - David's not the only Jumper out there. And he's on someone's hit list. Pursued by dedicated assassin Roland (Samuel L Jackson), David hooks up with fellow teleporter Griffin (Jamie Bell) and begins to learn more about his extraordinary gift. Director Doug Liman (The Bourne Identity) turns in a youthful adventure that plays on adolescents' thirst for freedom from responsibility (and the limits of geography), while establishing a workable mythology with one eye on a future franchise. The global jumping lets the production team set up fight sequences on the Sphinx and car chases through Tokyo, but Liman disappointingly underplays ideas about the corrupting consequences of power in favour of maintaining a hip, cool edge.
