In an interview with Yahoo! Movies, director Zack Snyder addressed rumors surrounding the upcoming Warner Bros. film "Batman v Superman: Dawn of Justice," specifically calling out the one involving his son Eli playing the Boy Wonder in a flashback sequence.
"There's a rumor that my son is [playing] Robin," Snyder told Yahoo! Movies. "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."
It's worth noting that Eli Snyder played young versions of Leonidas and Rorschach in Snyder's "300" and "Watchmen" films and also had a small part in "Sucker Punch." Also, while Snyder may say the rumor is false it certainly doesn't actually mean it is.
The truth about "Batman v Superman: Dawn of Justice" and the Boy Wonder will be revealed for certain when the film opens on March 25, 2016.
