Of course, going from the big screen to a mobile game is fairly easy and done all the time. Making the jump the other way is extremely rare. The only other mobile game to even start towards being made into a movie is Angry Birds, which is a game that has been an international sensation and has far more brand awareness (through a crazy amount of merchandising) than does Temple Run.
But, Temple Run has a big name producer attached - David Heyman, who was a producer on all eight Harry Potter movies, as well as I Am Legend and Gravity - and it has the backing of Warner Bros. studio. Not surprisingly, the movie would be about a man who steals an idol from a temple and then is chased by "demonic forces". So, it's basically planned to be a 90-minute version of the opening scene to Raiders of the Lost Ark.
Still, the project doesn't have a writer, a script, a director, or a cast; so, there's only a limited chance it will actually get through to production and release.
