Trailers for Warner Bros.’ holiday comedy Fred Claus are up online, and while the teaser trailer — essentially just a couch-set fraternal conversation between Paul Giamatti’s Santa Claus and Vince Vaughn’s overshadowed brother — gives off a good vibe, the full-fledged version plays like something made much more for the Tim Allen set. Marauding elves are to be expected in any Christmas comedy that travels to the North Pole, I guess, but the broad slapstick stuff came off as just dispiriting, and there’s no particularly well defined two-way friction (that is, the stuff of comedic conflict) between Vaughn’s Fred and other characters. It comes off, here, at least, as a one-man performance piece, and that — despite my affection for Vaughn — could get very old very fast.
