WAIT. Maybe they decided that since Javert was meant to be an "evil" character (for a 'kid-friendly' thing, they cannot make a character in the grey zone, it's evil or good and no in-betweens, bitches!), they would make him so ugly and non-canon that no one would be sorry to see him jump into the Seine. Kind of like the way Valjean doesn't really have a mouth, just a moustache that moves around when he talks. I was just waiting for him to shave the damn thing off.
