A film by the same title, released on February 14, 2008, was directed by Doug Liman, with a screenplay adapted by David S. Goyer, Jim Uhls and Simon Kinberg. It starred Hayden Christensen, Samuel L. Jackson, Rachel Bilson, Jamie Bell, and Diane Lane. The beginning of the film follows the early plot of the novel with respect to David's home life and discovery of jumping, but deviates significantly from there. Most of the characters are presented differently than in the book, and the film introduces another Jumper, Griffin O'Conner. Also new are a group, the Paladins, who hunt and kill Jumpers on religious grounds; Cox's character, renamed Roland Cox, is not an NSA agent, but rather the leader of the Paladins.
