Ezra Miller appears to have his hands full at the moment. While busy promoting “Fantastic Beasts and Where to Find Them,” the 24-year-old actor also took to social media to tease fans of his The Flash role in the upcoming DC Comics superhero flick, “Justice League.”

On Thursday, Miller took to Instagram to share a snap of his role as Barry Allen and the character’s metahuman alter-ego, The Flash. Though this is not the first time that fans could check out his version of the Scarlet Speedster since he did cameos for “Batman v Superman” and “Suicide Squad,” Miller made this extra special by teasing fans that “Justice League” is premiering in cinemas exactly a year after he posted the snap on Nov. 17, 2016.

Miller’s little teaser seemed to serve its purpose well, because a couple of fans responded to it on a positive note. One fan commented: “I can’t wait to see how you’ll do.” Another fan wrote: “It’s hard to deal with this… 1 whole year…”

Even though fans are sad that Miller won’t be gracing the big screen as Barry Allen-slash-The Flash anytime soon, he is appearing in David Yates’ “Fantastic Beasts and Where to Find Them” that is set to premiere in the U.S. this Friday. In the fantasy film that chronicles the adventures of Eddie Redmayne’s Newt Scamander, Miller plays the role of Credence Barebone. 

In one of his press interviews for the magical flick, Miller admitted that playing Credence is “one of the most exciting things that’s ever happened to me — to dive into this mythology that was my upbringing,” as quoted by Chicago Sun Times

Given his commitments with “Fantastic Beasts,” “Justice League” and his standalone “Flash” movie for 2018, it may seem that there is nothing that Miller can’t do at this point. Interestingly, there is really one thing that he can’t do as of the moment, and it’s signing a Marvel comic book. 

A fan-taken video of Miller is currently making rounds on the Internet after it was uploaded on YouTube early this week. In the clip, an awkward but apologetic Miller could be seen turning down a fan who had asked the actor to sign an “Agents of S.H.I.E.L.D.” comic book. Since the material was from Marvel, Miller was reluctant to sign it because of his DC/Warner Bros. engagement. 

“You understand why I can’t sign that, right? Find me something else and I’ll sign it. I can’t sign that. It’s so obvious that I can’t sign that. I’m sorry,” Miller tells the fan in the clip. When the fan asked if “Justice League” is from Marvel, Miller did not hesitate to explain that it is from DC. Because of his gesture, Digit Spy applauded the actor for showing his loyalty to DC.
