It might be that Christmas is the time of year when we're inundated with tinsel and Christmas tunes, but it's also the time when Sundance starts announcing their killer line-ups for 2010. This year's festival will run from January 21 to 31in Park City, Utah, and as always, Cinematical will be there to kick off the new festival year and cover all the great films that premiere.

The first announcement covers Sundance's US and World Competition Lineups, with more to follow later. This year boasts a slew of buzz-worthy fare, a lot of which we've been dying to see. The U.S. Dramatic Competition will screen Hesher, Spencer Susser's tale of a trickster that descends upon a struggling family, which just so happens to star Joseph Gordon-Levitt and Natalie Portman, Howl, the eagerly anticipated look at the obscenity trial that followed the poet's famous work (Rob Epstein and Jeffrey Friedman directing James Franco, David Strathairn), and actor Mark Ruffalo's directorial debut Sympathy for Delicious, starring Orlando Bloom as a recently paralyzed DJ who becomes a faith healer.

The Documentary selections include Alex Gibney's CASINO JACK & The United States of Money, plus additional fare ranging from Amir Bar-Lev's I'm Pat _____ Tillman to Tamra Davis' look at art with Jean-Michel Basquiat: The Radiant Child. Topping that off with world cinema, we've got foreign docs from names like Jose Padilha, and narrative films like Peepli Live by Anusha Rizvi.

See the full list after the jump and stay tuned for more slates, ones that -- we're hoping -- will include the latest from Michael Winterbottom and Mark Romanek.
