10. Fred Clause (Paul Giamatti)
It's hard to relate to Santa, what with his ability to control time, his 9 magic pet reindeer, and his hot wife. Nick, as he's called in Fred Claus, is kind of the everyman's Santa, who can be kind of a douchebag every now and again, just like all of us, and who doesn't shy away from a fistfight with his bum brother at Christmas, just like all of us.
9. The Chronicles of Narnia: The Lion, The Witch, and The Wardrobe (James Cosmo)
A pretty minimalist version of Santa, who shows up without much of a fanfare, gives the kids some [resents, then gets out of there. Presumably because there's a big battle coming and he's a total sissy. That or he doesn't want to be upstaged by the talking Jesus Lion, which is definitely a cooler thing to have in a movie.
8. Bad Santa (Billy Bob Thornton)
Of all the people you'd cast as Santa in your movie, Billy Bob Thornton is probably not very hight on that list. Then again, people said the same thing about casting him as the President in Love Actually. The trick to both of these was to rewrite the character as an arrogant sexist, or just forget the script entirely and let him do what he wanted on set. It's hard to tell which they went with.
7. Miracle on 34th Street (Richard Attenborough)
It's pretty much a given at this point that Santa's probably not real, but that doesn't stop the entire City of New York legally declaring Santa real just to spare some nice old guy from going to jail. In the end, isn't that what Christmas is all about?
6. How the Grinch Stole Christmas (Jim Carrey)
Most movie Santas are there to be wise, kindly, and fix things with their secret spells. It's kind of the other way round for the Grinch, who becomes Santa to ruin everything for everyone, then gets brought round to the true spirit of the holidays by Taylor Momsen at the end of the film. A truly modern take.
