Loki star Jonathan Majors felt the full force of boxing while filming Creed III.
He's set to enter the ring as Michael B Jordan's adversary Anderson Dame later this year, following in the footsteps of Tony Bellew's 'Pretty' Ricky Conlan and Florian Munteanu's Viktor Drago.
To become a convincing athlete, Majors had to get in serious shape, but he didn't expect his hands to gain so much size.

"Over time, they just got bigger and bigger," he told Variety.
Despite no doubt laying hands on Jordan's Adonis Creed, Majors himself "got punched in the face about 100 times, but it's all OK!"
If Kang the Conqueror turns up in the MCU with swollen eyes, we know why.
In other Creed III news, star-cum-director Jordan previously explained why Sylvester Stallone's iconic Rocky Balboa won't be appearing.
"I think that Sly let it be known that he wasn't coming back for this one but I think, you know, his essence and his spirit... there's always going to be a little bit of Rocky within Adonis.

"But this is a Creed franchise, and we really want to build this story and this world around him moving forward," he said.
"So, it's always respect and always a shit-ton of love for what he's built, but we really want to push and navigate Adonis forward and the family that he created. So, hopefully you guys will love what I'm thinking... what we're cooking up.
"I think it's going to be something special."
Stallone's next big-screen character arrives this August, in Julius Avery's Samaritan.
Creed III will be out in cinemas on November 23.
