Continuity mistake: When Cole and the halfbreed duel with knives, the fabric they hold in their mouths as a tether keeps flipping over, meaning the end of the cloth hangs out the left side of the mouth, then the right, and left again - several times for both actors - even tho the fight is continuous and they make no moves that would change this.
Continuity mistake: Near the beginning of the film, Bill Murray takes a seat front-row-center in court. Moments later, he's doing push-ups in the corridor. A few moments later, he's back in the same seat front-row-center in the courtroom.
Continuity mistake: When Shad and Nanelia are kissing, her right ear is covered by her hair, in the next shot her hair is now tucked behind her ear, and in the next shot, her ear is now covered again.
