According to Box Office Mojo, Monsters University has been pushed back to June 21, 2013, half a year after its scheduled premiere.
This news may come as a shock to fans looking forward to the prequel, especially after a large amount of news recently broke on the subject. Previously titled Monsters, Inc. 2, the film had a November 2, 2012 release on the calendar.
Just last week, it was revealed that rising star Dan Scanlon would step up as director. Mater and the Ghostlight (also directed by Scanlon) is one of my favorite movie-based short films, so I think the second installment in the Monsters franchise is in good hands— even if it may take a little longer.
