We’re still weeks away from Fall 2009, but the big screen battle for Winter 2010 has already begun.

As of today, there are at least four movies scheduled to open on December 17th of next year. Competing against The Smurfs will be a live-action adaptation of Yogi Bear. Meanwhile, Michel Gondry’s The Green Hornet will now face off against a highly-anticipated sequel from Disney.

Just days after Hornet was moved to the December slot (it was previously set to premiere on July 9), the Mouse House announced that it intends to debut Tron Legacy on that same date. The movie, which would once again feature Jeff Bridges, is a follow to the 1982 sci-fi adventure. (You can view the teaser trailer here.)
