9. Zack Snyder's Son Is Robin
Zack Snyder himself has shot this one down. Back in the summer, a rumour went around claiming that Snyder's son, Eli, would be taking up the mantle of Robin in a flashback scene in the movie. Snyder then trolled the world by posting a photo of himself and his son on Instagram* with the description 'Boy Wonder?'. The character's suit at the very least is expected to make an appearance, if we're all interpreting the Comic-Con trailer right. But Snyder's since come out and firmly denied Eli will be playing Robin. And while sometimes you can't trust what directors and cast members say, this definitely seems legit. Eli's had a few small appearances in his dad's movies, playing the young Leonidas and Rorschach in 300 and Watchmen, as well as a soldier in Sucker Punch. But those roles are nothing like the kind of potential playing Robin brings with it - the possibilities of further appearances that require actual lines of dialogue - so chalk this one up to the rumour mill. *In fairness to him, Snyder's Instagram is actually private so he could have just been making a joke about the rumour with his friends. But the film's still photographer Clay Enos
reposted it, leading to everyone reporting that Snyder had confirmed said rumour.
