"It literally is my dream. I'm playing a superhero, but that's still not my dream job."

No, Jason Momoa's dream job isn't suiting up as Aquaman in Justice League, before starring in his own solo film -- it's directing commercials for clothing line Carhartt, a gig the 36-year-old actor-director has been tasked with for three years now. Their latest spot may be the most ambitious yet, featuring World War I battlefields and bucking broncos.

"I love getting in with real people and getting them and capturing them in their real lifestyles," Momoa tells ET of working with real-life mechanics and cement cutters for the commercial. "They're looking at me, going like, 'Dude, I love you! You're Drogo!' And it's nothing but me. I get to get down there and be with them and inspire them."

The Game of Thrones star is a hands-on director behind the camera, as you can see in exclusive behind-the-scenes footage from the commercial, which shows him running through the trenches alongside stuntmen.

"I love when I'm in the s**t and I'm freezing my a** off and the director takes his coat off," he explains of his directing style. "I want to feel what my actors are going through, too...If you build a beautiful net to catch people, you can trust the director and really leap. That's a great feeling to have as an actor. So, what I try to do as a director is be a general."

Momoa will be back in that "s**t" soon, as cameras start rolling on the first Justice League movie next week. What he looks forward to most about teaming up with Batman (Ben Affleck), Superman (Henry Cavill) and Wonder Woman (Gal Gadot) onscreen won't surprise you -- it's the action.

"I like fighting. So, I'm looking forward to being a superhero and just fighting," he teases. "There's some good battles."

After that, Momoa will front his own Aquaman movie, set to hit theaters on July 27, 2018 and directed by James Wan (Furious 7). When we asked what will surprise fans about the movie, the King of the Seven Seas himself compared it to...a Marvel movie?!

"It's just something that hasn't been explored before," he reveals. "For me, it's like Iron Man. When Iron Man came out, it was like, 'Wow!' We haven't explored that character before and Robert Downey took it to a whole nother level. He's genius and it was amazing. I loved it."

ET recently confirmed that Amber Heard will join Momoa as Aquaman's wife, Mera, and though he says they have not had a chance to "really get in there and break it down yet," he tells us, "I'm super stoked. She's awesome!"

One thing he does know for sure is that he has no plans to step behind the camera of a future Aquaman installment. "Noooooo way!" he replies with a laugh. "I don't think I could do it. Props to all the directors who do these movies, but it just baffles me. I'm excited to experience it on Justice League, I've never been on something quite this size."

One of the responsibilities of directing one of these superhero tentpole movies is dealing with backlash, something Batman v Superman: Dawn of Justice director Zack Snyder experienced when the movie hit theaters to polarizing reviews and endless fan opinions.

"There's been some things here and there, but I'm stoked. There's a lot of support from fans," Momoa says of the backlash. "There's a big beautiful world. There's a lot -- a lot -- of stuff. I feel really privileged to know that there's a lot of big, beautiful stuff that's going to happen. I'm excited too, for people to see the final product. And now it's our turn -- it's Justice League time! I've been waiting for four years that I've known about it that I've had to keep my mouth shut. I'm super pumped to shoot it!"

"Some people liked it, some people didn't, it is what it is," he added. "I don't get it, but I don't really listen to what anyone says...You can't win 'em all. And I had a ball. I loved it."
