I believe by the time Lanning gets to doing films based upon his vision then there will be no need for games. If you think about it Oddworld is about the stories of the inhabitants and Lorne Lanning wants to produce those stories in what ever media suits the story best. The thing with OWI these stories we see now are better suited for the gameing media as oppose to major motion pictures. It all depends on the nature of the story. Lanning's vision is so complex that its going to take more than games to tell the full tale of Oddworld with.
And plus OWI doesn't need to split if they do films and games because makeing video games are not that far from makeing a motion picture. The difference is your putting all the elements into a game ingion. The rest is pretty much makeing a movie. And that is what OWI does before they turn it into a game. Movies on the otherhand don't involve putting elements or animations into an ingion of some type. Its pretty much everything done in principle photagraghy and setting up frames and adding the special effects.
