Although it hardly matters in a situation like this, Marvel technically laid claim to this release date first, announcing in June that they will release a then-untitled movie on May 6, 2016. Batman Vs. Superman was initially slated for a July 17, 2015 release, before Warner Bros. pushed their sequel into the summer 2016 date back in January.
Also weighing in on the matter was Alan Gould, an analyst for Evercore Partners LLC in New York, who revealed this would be a lose-lose situation for the studios and the theaters if one project didn't switch their release date.
Chris Aronson, 20th Century Fox's president of domestic distribution, also offered a statement about this scenario.
Marvel already revealed last month that they are keeping the May 6, 2016 release date, but something has to give between now and then. Which project do you think it will be? As of now, there are currently two open weekends in May 2016 (May 13 and May 20), but Fox also has their own superhero sequel, X-Men: Apocalypse, scheduled for May 27, 2016. Other summer 2016 dates that are unoccupied are June 3, June 24, July 22 and the entire month of August.
Batman v Superman: Dawn of Justice comes to theaters May 6th, 2016 and stars Henry Cavill, Ben Affleck, Amy Adams, Diane Lane, Laurence Fishburne, Gal Gadot, Jesse Eisenberg, Jeremy Irons. The film is directed by Zack Snyder.
