1. Bale suits up
Every mo-cap suit is adorned with 76 specifically placed markers, which are rather disappointingly just rubber balls affixed with that reflective stuff you get on police jackets. Rather cleverly, though, each suit has one misplaced on purpose so the software can detect multiple people at once. Suits at EA's motion-capture HQ are specially fitted by height and weight – and then kept in the world's strangest cloakroom in wait for someone of similar proportions.
