Warner Bros. Pictures set the stage for the biggest superhero showdown of all time back in January when it announced that the Man of Steel sequel Batman vs. Superman had been pushed back to May 6th 2016 – a date that put it head-to-head with Marvel Studios and the now confirmed Captain America 3.

It is of course hugely unlikely that these two comic book movie titans will open on the same day, but so far both Warner Bros. and Marvel Studios have refused to budge, but now it seems the first cracks are showing in Marvel’s armor, with Variety reporter Brett Lang quoting Disney chief Alan Horn as stating “we’ll see. We’re struggling with it” with regards to the big face-off.

So, might Marvel Studios be the one to blink first in the showdown between Captain America and the World’s Finest?
