Warner Bros. has pushed production on the untitled "Superman-Batman" movie to the second quarter of this year and it will now be released on May 6, 2016.
The Peter Pan origin story "Pan" is being put in its place on July 17, 2015. "Superman-Batman" will now square off against a Marvel film which Marvel has still not announced.
The film is still in pre-production with Henry Cavill set to star alongside Affleck, and Zack Snyder is on to helm.
In a statement, Warners said the decision was made to "help fully realize the vision." Warners is still casting the film including the main villain role which sources tell Variety is still in Joaquin Phoenix's court.
This marks another film to leave what was turning out to be a very crowded 2015 summer, with "Pirates of the Caribbean 5" and the new "Star Wars" also moving out of the frame.
One continuing moving part is what this means for Affleck and his always busy schedule. Affleck was planning on directing "Live by Night" following production on "Superman-Batman," with Warners already dating "Night" for Dec. 25, 2015.
It now seems unlikely that Affleck would be able to jump into the director's chair before the end of 2014, which would put pressure on getting the film done on time in order to meet WB's deadline.
'Batman-Superman" will also reunite "Man of Steel" stars Amy Adams, Laurence Fishburne and Diane Lane, and also stars Gal Gadot as Wonder Woman/Diana Prince.
The screenplay will be written by David S. Goyer, from a story co-created by Goyer and Snyder. Charles Roven and Deborah Snyder are producing, with Benjamin Melniker, Michael E. Uslan and Wesley Coller serving as executive producers.
