In addition to the just-announced release dates for Independence Day 3D, Dawn of the Planet of the Apes and the still-untitled X-Men: First Class Sequel, 20th Century Fox has scheduled and rescheduled dates for Steven Spielberg's Robopocalypse, Ben Stiller's The Secret Life of Walter Mitty, Paul Feig's Untitled Sandra Bullock and Melissa McCarthy comedy, the franchise sequel Percy Jackson: Sea of Monsters and the 3D project, Walking with Dinosaurs.

Robopocalypse, featuring a screenplay by Drew Goddard adapted from Daniel H. Wilson's book, will see a release on April 25, 2014. There are currently no other films being released that day.

The Secret Life of Walter Mitty, directed by and starring Stiller, will arrive on Christmas Day, 2013. That puts the comedy up against the tentatively-scheduled Ninja Turtles reboot.

The Feig comedy is set for April 5, 2013 and is the first to claim that weekend.

Percy Jackson: Sea of Monsters, originally scheduled for March 27th of next year, will now bow on August 16, 2013. It, too, is currently the only film scheduled for that weekend.

Finally, Walking with Dinosaurs, previously set for October 11, 2013, will move two months to December 20th. That's one week after Warner Bros.' The Hobbit: There and Back Again.
