Trailers for some upcoming Sundance Film Festival 2010 offerings are starting to pop up online.

First Showing has one for “Boy,” a World Cinema Narrative Competition film from New Zealand, written and directed by Taika Waititi. It involves an 11-year-old with a Michael Jackson fixation and an oddball absentee father who suddenly returns. The off-center humor looks appealing.

Apple has exclusively put up the one for “Frozen,” a Park City at Midnight selection that Anchor Bay has already picked up for U.S. distribution. Anchor Bay will open it in theaters February 5, two weeks after its world premiere at the festival. It looks like a nice, freezing-cold variation on the trapped-in-a-miserable-situation subgenre.
