If you can see the movie screen, it will be in the output image...but 
that's too obvious, and probably not what you're asking. There is no way 
to "grab" light projected on a surface as an image, short of pointing 
the camera at it.

Please...rather than guessing at different ways that *might* work and 
asking if they are possible, why don't you just explain what you are 
trying to accomplish? It sounds like you are trying to do forward 
raytracing, where light is traced from the light sources, through the 
scene, and into the camera. This is technically possible, but quite 
infeasible: the number of rays required is simply too huge, and it takes 
an extreme amount of time to generate an image.
