The Rumour: Though the most prevalent rumour regarding Robin was that Jena Malone was playing a female version of the character before her Barbara Gordon role was confirmed, the silliest Robin rumour came in the form of the Boy Wonder being played by director Zack Snyder's 18-year-old son Eli. This picked up traction after the movie's set photographer posted the above picture on Instagram with the caption, "Boy wonder?" Fans then began to speculate that Eli may play Robin in a flashback sequence. How Likely Is It?: 2/10. Snyder has cast his son in small parts in his movies before so we can't rule it out completely, but the director himself has refuted the claim, even if it wouldn't be the first time a filmmaker lied to our faces. Not impossible, but not likely, and we really don't want this sort of nepotism to seep into the DCEU.
