Jason Momoa On Friendship With Dwayne Johnson, 'Dune' Filming Experience

Jason Momoa has opened up about his friendship with Dwayne "The Rock" Johnson.

The "Aquaman" star, 42, shared during a recent interview with Entertainment Tonight that he and the "Black Adam" actor, 49, bond over fatherhood.

"Oh, it's just like two dads," Momoa told ET when asked what their friendship is like. "It's really cool. Even the same thing with [Chris] Hemsworth, you just kind of go like, you're just buds."

Momoa shares two kids with wife Lisa Bonet — Nakoa-Wolf, 12, and Lola Iolani, 14. The "Game of Thrones" star is also a stepfather to Bonet's daughter, Zoë Kravitz, 32, from her first marriage to musician Lenny Kravitz.

Meanwhile, Johnson shares daughters Jasmine, 5, and Tiana, 3, with his wife Lauren Hashian. He is also a dad to 20-year-old daughter Simone Alexandra with ex-wife Dany Garcia.

During the interview, ET showed the sweet personalized video message Momoa sent to Johnson's daughter Tiana, who is a fan of Aquaman, when she turned 3 years old in April.

"I'm sorry I couldn't be there, but I love you and tell your papa that I love him too," Momoa said in the celebratory video. "I'll see you soon, happy third birthday. Bye Jazzy, bye Tia, love you."

Speaking about the sweet gesture, Momoa said it wasn't a big deal because he and Johnson were friends, before going on to praise his pal. "I feel like he's doing a lot of good things for the planet. And he's a good father and I'm equally trying to do the same," he added.

This wasn't the first time Momoa had spoken about Johnson, with whom he has been pals for almost 20 years after meeting in Hawaii through a mutual friend. During an appearance on "The Tonight Show Starring Jimmy Fallon" in June, the actor voiced his hopes that they will be able to make a movie together when the time is right.

"We tried to get together and make a movie together, but it's just he's way busier than I am and I'm pretty busy right now so, one of these days!" Momoa said.

Meanwhile, Momoa described his time filming his new movie "Dune" as "the greatest experience."

"I can't believe I'm even in this movie. It's amazing to even be part of this and then work with my idol," he said, referring to director Denis Villeneuve.

Momoa called Villeneuve "my favorite director in the world." He also expressed his joy for the opportunity to work with incredible actors like Javier Bardem, Oscar Isaac and Josh Brolin.

Momoa revealed that he has already seen "Dune" three times, gushing that the film kept "getting better" with each viewing.

As for his training and preparation for the fight scenes, Momoa — who plays Duncan, a powerful swordmaster who serves House Atreides and is dear friends with its future leader Paul (Timothée Chalamet) in the film — credited his stuntman for protecting him and helping train him. He added that they just made sure to never hurt anyone.

"Dune" is now showing in cinemas and streaming on HBO Max.
