6. Bad Santa (2003)

Billy Bob Thornton is Bad Santa; the crafty Christmas criminal who doesn't care if you're naughty or nice! Although initially Billy Bob Thornton is presented as a drunk and disorderly criminal who robs malls during Christmas (with partner Marcus the 'elf'), he does show a glimpse of a softer and less immoral side to his character. One of the occasions being helping troubled kid Therman Merman through some confidence and peer pressure issues. Not-so-bad Santa indeed. A decade later, the sequel Bad Santa 2 is due to be released in 2013 with Billy Bob Thornton reprising his role as Bad Santa Willie T. Stokes.
