Justice League's Jason Momoa and Ezra Miller on ridiculously heavy costumes and cut scenes

Ever hear about the time super friends Aquaman and The Flash were hanging out in Wonder Woman's office at the Louvre? Maybe not, but it did happen last week when SYFY WIRE spoke with Justice League stars Jason Momoa and Ezra Miller about the new movie.

Sitting in the Wonder Woman-themed room of a Justice League installation in London, Momoa and Miller joined SYFY WIRE to talk about their roles as heroes — one reluctant, one eager — in the DCEU super-team movie. Although both actors pointed out that while they play Arthur Curry and Barry Allen in the film, opening November 17, they aren’t quite Aquaman and The Flash – yet.

Super friends in real life, the duo talk about their on-screen relationship in the interview below, as well as the role of humor in the film. Momoa, appearing in next year's James Wan-directed solo film Aquaman, also addresses fans who may be concerned his Aquaman isn't one they recognize. They also reveal a deleted scene involving their characters and offer up tips on getting fitted for a super-suit.

How would you define the relationship between your characters in this movie?

Ezra Miller: In real life, Jason is like my brother. I think the world of him, and trust him implicitly. In the movie, where Aquaman and Barry are at, I think Barry is a little afraid of him, and Aquaman is annoyed by Barry. Slightly different dynamic, but both brotherly.

Jason Momoa: The hardest thing was not giggling because he always has fresh ideas, and Ezra is always top game. There is a lot of beautiful improv, and I have to keep a straight grumpy face. I am generally a smiler, and I giggle, and enjoy laughing. But these guys are f***ing hardasses. But we had fun on set.

There is a lot of comedic beats in the film. We expected some with Barry, but Aquaman also has his funny moments in this movie. Were you surprised by that initially?

Momoa: It is situational. The comedy comes at the highest stakes where sh** is hitting the fan, and I'm having a ball. And Barry is being completely honest when the fear is there, and that anxiety is funny. When the stakes are high, they have two different perspectives that bring humor to it.

Miller: I like how everyone in the League have their moments of humor. But it is real to life. If you talk to first responders, they can have the most cavalier attitude about what, to us, would be this most mortal peril. For them, they're joking when paramedics are driving to the scene. You make jokes to deal with things that are hard in life. Everyone in the League was riding that balance of tone. I feel like some people expected Barry being the jokester -- which would ultimately be annoying, and distracting if you had just one character totally of a separate tone than the rest of the film.

Jason, you said that you are Arthur Curry in this, but not yet Aquaman. So is Justice League the beginning of your evolution into the character we know?

Momoa: Yeah, I like the way this went. Zack [Snyder] made this vision. It was his idea to make Aquaman this way. And then, when James Wan came on, he had this beautiful story. You get to see how he fit with what Zack's original idea was to get him there. I love how it started with the team. Uber Aquaman fans might go, "That's not my Aquaman, my Aquaman doesn't drink …" They're going to have these hiccups, but there is a whole generation that doesn't know anything about Aquaman. They will hopefully like him.

Miller: I also think true Aquaman fans are going to find, in Jason's depiction, a version they have always wanted but never had. I theorize that Jason's film performance will be one of the only film performances of a comic book hero in history to permanently change that hero in the comic history. You can't move backwards from where Jason takes this role. A cooler Aquaman. I don't know if we can go back to blonde, wussy Arthur Curry after Jason.

Momoa: Yeah, it's not like just putting a cowl on.

Speaking of cowls, what are some tips to choosing a super suit?

Momoa: Me and Ezra were pretty smart, because we go in for wardrobe fitting quite often. I am obsessed about getting my characters to look right. I also want to be very comfortable, and be able to get the f*** out of it quickly. I learned from Henry [Cavill] that he was locked in that thing through Man of Steel. That ain't me, because I'm going to bitch and want out. I get really hot, and when you're doing all that fighting, you're going to sweat. They shoot Henry through the air, but I'm going to be moving, and fighting, and sweating.

Miller: I sacrificed being able to get out of it for more mobility and functionality – which was hard to achieve with The Flash's suit because of how many interconnected parts it had. The wardrobe department put in an incredible, insane amount of work to make it possible to just move in that thing. But Ben's Batman cowl is one piece of rubber, and his cape is like 50 pounds.

Momoa: Mine is about 33 or something like that.

MIller: Aquaman's and Batman's are the heaviest suits.

You need to train hard just to carry those things around.

Miller: You see these dudes train really hard, and you see Jason train his ass off, not only to have the appearance of a superhero but to be able to pull off stunts in a harness rig in that suit. It requires a lot of bodily strength. It is really cool to see everyone's discipline. Showing up on set and saying your dialogue is one thing, but when you see everyone's commitment to the training that is painful, that is demanding, that you have to do every day, it blows my mind.

Momoa: The hardest thing is you do a scene, then you break it down, and it takes half an hour to reset the shot. You have to stay warm, so I have to keep stretching because that hot/cold s*** is when you get hurt. You constantly have to be ready, be warm, when doing those fight scenes. You can't just go relax. You have to constantly have someone working on you.

Will you reveal any scenes that didn't make the final film?

Momoa: There is this funny moment when we are in a van. We just call him Barry Allen in this. He's not The Flash yet; he hasn't donned the name. But we were trying to give him a name. We were going to have a scene where I was hoping I'd get to call him that. He is in the back coming up with "Lightning Boy" …

Miller: I was like, does it have to be an alliteration? Maybe Lightning Lad? 

Momoa: And I say, "How about Motor Mouth?" because he's just sitting there eating, with food spitting out. It is the cutest, perfect scene.

Miller: I go, "Oh yeah, how about Comedy Man?"

Momoa: There's a lot of great moments that didn't make the movie but we had a ball doing.

Miller: There was also a challenge to see how many burgers I could eat. We did the whole scene in one take, and there was this burger challenge. I thought I could do like five. I ended up doing two, at best. It was painful.

[Note: And by the way, "Lightning Boy" and "Lightning Lad" are aliases of Garth Ranzz, an original member of the Legion of Superheroes. So, sorry, Barry, but those names are taken!]
