Picnic Films, which produces short documentaries and educational/corporate films, recently posted this video that takes viewers to NaturalMotion's Oxford office and introduces them to how knowledge and manipulation of physics, gravity, and momentum play into video game development.

NaturalMotion's Euphoria software for animating 3D characters is used in a number of popular titles, like Grand Theft Auto IV and Red Dead Redemption, and you can see it in action here to show how physics plays into Back Breaker -- there's a fun bit that shows what playing football on the moon might look like, too.

According to Picnic Films, NaturalMotion's CEO Torsten Reil agreed to take part in this film because he was "fed up with young graduates applying to his company for jobs with the wrong qualifications" and wanted to stress that programmers "need a degree in maths or physics" to work in the gaming industry.

Or, as mentioned earlier, $0.99 should be enough to get you started.
