Unfortunately, this isn't some kind of pullover-based fetish porn story. Instead, it's about Jamie Bell, star of movie Jumper, doing the VO the game's lead character, Griffin.
Jumper: Griffin’s Story extends the film’s storyline, following Griffin, "a battle-hardened Jumper determined to avenge the death of his parents at the hands of the Paladins."
This is actually out tomorrow, according to the press release, for PS2, Wii and Xbox 360. Bet it's awesome.
