You've heard about the War on Christmas; well, this just-as-fictional movie takes it to a new level, pitting Batman against the S-man with red in his costume: Santa.
The fight will be tough for the Dark Knight, since he has to contend with someone with mythical status, superhuman speed, shapeshifting, and a whole contingency of magical beings backing him up. Look out, Batman, you might be in trouble.
Of course this comes from Funny or Die, because they're the only ones crazy enough to mash up Batman v Superman with The Santa Clause (and some of the sequels, too, I'm pretty sure). This is the Christmas movie we deserve.
