Batman v Superman: Dawn of Justice may have released an epic trailer during Comic-Con weekend, but it remains one of the most secretive superhero movies of 2016. However, despite the title, other DC Comics heroes will also be making an appearance. Those include Aquaman, The Flash, and Wonder Woman, but is that going to leave the movie too stuffed?

“I try and stay central,” director Zack Snyder told Yahoo Movies in a recent interview about the film. “There’s something really fun about bringing the other characters in, but it’s really about staying central to the real core mythology is what I think the audience enjoys most.”

The secrecy mentioned above has obviously led to a lot of rumours and speculation about what’s to come, including recent reports that Snyder’s son is going to play Robin in a brief flashback depicting the death of Batman’s sidekick at the hands of Jared Leto’s Joker. However, the filmmaker isn’t letting the rumours get to him and finds them rather amusing:

“There are so many, it’s insanity. It’s funny because every now and then someone will touch on something that’s kind of true, but the next thing they say makes me realize that they took a wild guess. They’ll say something and I’ll say “Oh snap, they must have seen the script.” And then they’ll say, “And this happens!” And then I’ll go, They have no idea what they’re talking about. It’s fun for everyone to speculate and take shots and think of things and try to sell it. There’s an industry in selling your guess. [People think], “I’m going to make a fake script and look like I read the real one.” What length are you willing to go?”

“There’s a rumor that my son is [playing] Robin. It’s not true. Now there are all these images of him that people have made where he’s dressed like Robin. It’s fun to hear and see them.”
