A fan also commented, “This is certainly a good morning 🔥,” while another added, “Hugh we are also f---ing grateful.”

Earlier this year, Jackman opened up to PEOPLE about getting his body back in superhero shape for Marvel’s Deadpool & Wolverine, which was released in July and saw him reprise his X-Men character for the first time since 2017.

“When I came back to it, it was really fun and I was thrilled. My body was a little sore at the beginning, but I was thrilled that my body was still responding. And I realized how good it is for your brain. But the hardest bit…the food,” Jackman admitted, adding that he’s always had trouble bulking up to become Wolverine.

“I have to eat a lot,” he continued. “For me, for my body type, I'm naturally skinny. To get the size on, that's the hardest bit. That's the bit that does my head in.”

“Yeah, the five, six meals a day, which sounds great to some people. I'm sure they're like, ‘Well, that sounds great.’ But it's not like the type of food that you would really necessarily enjoy,” added Jackman’s costar Ryan Reynolds, noting that he “couldn’t believe” the physicality he saw from Jackman while they were filming.

Costar Rob Delaney also shared that he was blown away by Jackman’s athletic build and his dedication to staying in shape for the part, which included rigorous daily push-ups.

During an interview Virgin Radio UK ahead of the movie’s release, Delaney, 47, said, “Hugh Jackman, right? He’s so ripped and muscular and sleeveless and often shirtless and that he’s a very nice guy. I thought that the superhero muscles in these movies were like cosmetics. Not that they weren’t literally on your body, but that they were more about show than strength.”

“Hugh Jackman would routinely drop to the floor and do press-ups. I saw him do 800 press-ups in one day, and they’re slow and perfect form,” he explained. “So literally, if a bus fell on you and he was there, you wouldn’t have to worry. He would promptly remove it from you and you’d be okay.”
