Also an image on film is the integration over the time the shutter was open, causing a very smooth motion blur. Games don't naturally have this motion blur, so low frame-rate movement appears choppy. Sometimes film makers reduce the length of integration (time the shutter is open) to produce a choppier scene. This was prominently featured in action scenes of the movie Gladiator. Many people did not like the effect because, like a low frame-rate video game, it was harsh and disorienting.
