Set for a cinema release in 2015 is a big-screen adaptation of the Ratchet and Clank videogame series. Perhaps the most surprising thing about this is there's a trailer already, on the day the project is being officially announced.
Production of the film is being taken care of at Rainmaker Entertainment, who recently gave us the long-delayed, Weinstein-afflicted Escape From Planet Earth. I don't think they're really been tested under fair conditions as yet.
The plan is to integrate – though no doubt also polish – assets used in the game animation to make the film more "authentic." I expect a consistency of voice casting too.
Sony have already adapted Heavenly Sword into a CG movie, and that one is expected to go straight to disc soon – I suppose it doesn't seem as big-screen appropriated as the Clank movie, likely because it won't be so "family friendly."
This particular game-to-film scheme could run and run. There's certainly enough videogame series with well known characters.
