Sci-fi, superhero movies set to dominate 2011

The Autobots and Decepticons will battle it out again, this time over Independence Day weekend in 2011.

Paramount has given "Transformers 3" a coveted July 1 release date for that year, despite the lack of director, script or signed stars, sources say. Despite opening the weekend after July 4, the first installment pulled in more than $70 million. "Transformers 2: Revenge of the Fallen" won't be waiting for the fireworks: It hits theaters on June 24 this year.

Marvel's "Thor," meanwhile, will move to May 20, 2011. Just last week, the movie was pushed back a year from its original 2010 spot.
