The techniques between film and real time are essentially the same. In both you need to know how to create efficient models, UV, rig, and animate. The only real difference is that when you're doing film work, you can use extra processes, such as advanced shaders, larger texture maps, etc.
The modeling process is a bit different as well for film, as you would generally want to keep your geometry as quadrangular as possible, as more often than not, you will end up smoothing the geometry, or even exporting it into zBrush for further detailing.
Imagination is more important than knowledge.
