Bad Santa stars Billy Bob Thornton as a con-man out for some quick cash. Of course nothing ever goes the way it's planned. Here's some mistakes to watch out for.

Sort of like changing water into wine - when Willy sleeps over the kid's house, he first gets a glass of water - which turns into orange juice.

Willy does more magic. In the bath scene, the towel on his face changes from shot to shot.

During the sneeze scene, Marcus changes shirts. First he has a green with red collar ... then he has green with blue vest.
