Ezra Miller can barely contain himself when talking about The Flash. “It’s a little intense for me because I get goosebumps just thinking about it,” Miller told MTV News over the phone. The 23-year-old actor is currently in London filming Zack Snyder’s Justice League, where he’ll star alongside Ben Affleck, Gal Gadot, Jason Momoa, Ray Fisher, and Henry Cavill as DC’s A1 superhero team.

After making two brief appearances as the Scarlet Speedster in Batman v. Superman and Suicide Squad, Miller is ready to front his own superhero adventure in director Rick Famuyiwa’s The Flash solo movie, which is set for release in March 2018. Though the film is in the early stages of production, there’s a sense that The Flash will deliver something previous films in the DC Extended Universe have lacked: humor.

“I think there’s just an intention to make something extremely fun and something superhuman and something deeply human,” Miller said. “It’s the thing we’re all trying to do, but I think Rick’s mind and his heart are in an excellent place, and his expertise as a filmmaker, as evidenced by Dope, all come together as very exciting factors to me.”

“It’s hard when talking about Rick to not use the word dope too many times,” he added. “It’s the Brooklyn in me; dope is a big part of my vernacular.”

At this year’s San Diego Comic-Con, Famuyiwa announced that Dope actress Kiersey Clemons would be joining the cast as Iris West, Barry Allen’s friend and future love interest. Though Miller can’t say much about his “tough-as-nails” leading lady, he did hint that their chemistry read was rather electric.

“Kiersey is amazing,” he said. “I had the opportunity to read with her and do some explorative acting in our chemistry read ... the results of these experiments clearly were positive. I’m just deeply excited about what these people carry in their hearts, and I’m excited about the radical intention that everybody seems to be bringing to the genesis chamber of this film.”

As for the other speedster in the DC universe, Miller said that he and fellow Flash actor Grant Gustin — who stars as the titular speedster over on the CW — have yet to meet but that “he can’t wait” to race him in the Speed Force.

“He’s a boss,” Miller said. “I can’t wait to see him, eye to eye, adrift in the Speed Force — our eyes will lock and, in that moment, we will both know the truth. What truth? I dare not say.”

However, Miller has spoken to one Grant in particular: Grant Morrison, comic-book writer and creator of the classic Batman story Arkham Asylum: A Serious House on Serious Earth. (Not for nothing, but Affleck is rumored to be working on an adaptation of Arkham Asylum for his solo Bat movie.)

“Grant Morrison is my absolute Guruji when it comes to The Flash and the mythos of the comic book — these two-dimensional realities that we engage with in our three-dimensional world,” he said. “Us trying to understand those beings is as ludicrous as those two-dimensional beings trying to understand us, and yet there’s something about The Flash that we can relate to on a uniquely human level.”

The Flash speeds into theaters March 16, 2018.
