Shane Acker the director of the film 9 is teaming up with Brown Bag Films and Valve to create his next film, Deep.
Brown Bag Films is best known for creating short films and children's animated television programs, and Valve is known as the company that adamantly refuses to make a game every body wants (Half-Life 3).
Deep is a post-World War III, post-apocalyptic, underwater adventure film being directed by Acker, and Valve's Source engine has been licensed to assist with animation.
"Valve's tools and technologies, based on its Source game engine, allow Acker and Brown Bag real-time rendering, and editing, simplified character animation." Working with the Source engine also allows for an easy transition to a video game based on the movie and Brown Bag is also looking at Steam as a possible distribution method for the film. Indie Game The Movie will be distributed on Steam, so it's certainly not out of the question.
