Warner Brothers has refused to budge in the game of box office chicken it is playing with Marvel Studios.

The studio recently announced that Batman Vs Superman - the working title for the sequel to Man Of Steel - would be postponed from 2015 to 6 May, 2016.

But Marvel Studios this week confirmed that Captain America 3 is slated for release on the same weekend, creating a box office battle royale.

And Dan Fellman, Warner Bros' president of domestic distribution, has now indicated that despite the potential impact on revenue, the studio won't be the first to blink.

He told Bloomberg: "It doesn't make a lot of sense for two huge superhero films to open on the same date but there is a lot of time between now and 5/6/16.

"However at this time, we are not considering a change of date for Batman vs Superman."

However Joe Russo - one half of the directing duo behind Captain America: The Winter Soldier - has said he thinks one of the studios will give way eventually.

"Everybody likes to imagine a flame war that'll start over this but it's not," he told Digital Spy.

"It's two big movies on a date - neither studio is crazy enough to eat up each other's profits. At some point, somebody's going to move off the date."
