Warner Bros. has pushed Bryan Singer's Jack the Giant Killer from June 15, 2012 to March 22, 2013. It isn't said why the switch was made, but Jack the Giant Killer will now go up against Sony's Captain Phillips and DreamWorks Animation's The Croods.

The studio has also moved the upcoming musical Rock of Ages from June 1 of 2012 to June 15. The only other movie slated for release on June 15 is the Sony comedy Donny's Son, which stars Adam Sandler and Andy Samberg.

Warner Bros. has also taken Arthur & Lancelot off its release schedule. It was previously scheduled for release on March 15, 2013. Joel Kinnaman and Kit Harington are attached to star in the medieval adventure from director David Dobkin.
