Sony/Screen Gems has pushed back the release of Underworld 4 from September 23, 2011 to January 20, 2012. Additionally, it is now back to being set for release in 3D. If you remember back to when the film was first announced, it was originally set for 3D release before being changed to a 2D release.
Other box office changes include: Focus Features’ It’s Kind of a Funny Story (10/8/2010–from 9/24/2010) and Universal’s My Soul to Take (in 3D) (10/8/2010–from 10/29/2010). Meanwhile, Reliance Big Pictures has set 8/27/2010 release dates for both Chakjawana and Aashayein (Wishes).
