Yes, Sony is, in fact, working on a film version of its long-running simulation racing video game series Gran Turismo. A Sony Computer Entertainment UK rep told our sister site Joystiq that said film is "being made," but provided no other information.
Yesterday, reports surfaced of the film being tied to Mike de Luca and Dana Brunetti (of The Social Network and 50 Shades of Grey production fame), with support from a trio of Sony Pictures execs. Of course, none of this sounds too far-fetched given the presence of Sony Pictures president Michael Lynton at the PlayStation E3 press conference. He promised Sony Pictures' support to the PlayStation 4 in the form of original programming, and a movie based on a massive PlayStation franchise sounds like a good start. For now, however, few details are confirmed beyond the project's existence.
