Conor McGregor picked up and flipped a Call of Duty dev during the making of Infinite Warfare: 'I wanted him to do something really physical, to demonstrate how capable he is'

Call of Duty doesn't have much luck with its stunt casting. Two years after Infinity Ward put Kevin Spacey in Advanced Warfare—before he was accused of sexual assault—it turned MMA fighter Conor McGregor into a future soldier, Captain Bradley Fillion, in Infinite Warfare.

McGregor's role was quite small, despite being one of the game's antagonists, and ended in his character's demise, but co-directors Jordan Hirsh and Taylor Kurosaki didn't want to cut any corners when it came to the mo-cap.

At the time, co-directors Hirsh and Kurosaki were trying to shake things up in regards to mo-cap. "I think that the folks at Infinity Ward probably thought I was a little crazy when I came in," Kurosaki tells us. "I think for every game they had done before that, you would maybe do some mocap or a cool takedown or a finisher, and then you'd have actors that would come into a VO booth and you'd have them come in one at a time and they'd read their lines and it’d be stitched together and then you're done. And they built a performance capture stage specifically for this project."

With Infinite Warfare, the team was doing full performance capture, so it needed its actors to get more physical.

Kurosaki remembers, after McGregor flipped him, that he "did this punch [right in front of my face] that I could feel the wind from. We're just rehearsing and figuring out the blocking. Everyone on the stage was, ‘Whoa, that was crazy! It was so fast!’ And of course, I had a different perspective than everyone else. Then everyone was laughing, and he helped me up, and I'm laughing. And then all of a sudden, this giant bead of sweat starts running down my face. I had this adrenaline, even though I knew I was perfectly safe. My body was just doing something that I couldn't control."

A few years later, McGregor started racking up criminal charges for assault. In 2019, he attacked a man for not accepting a drink in a Dublin pub. He pleaded guilty. In the same year, police in Ireland started investigating McGregor over allegations of multiple sexual assaults. He was not prosecuted, but a civil claim was made against him by Nikita Hand. In 2024, an Irish jury found that McGregor raped Hand.

Also in 2024, McGregor starred in Hitman, as one of its celebrity Elusive Targets—his second videogame role outside of the UFC games. IO Interactive stopped working with him after the ruling and removed him from the game as an Elusive Target.

Activision, unlike IO, left McGregor in the Infinite Warfare campaign. The fighter has not made any other videogame appearances since then. Prior to the ruling, he was a playable fighter in EA's UFC games, starting in 2014. He was the co-cover athlete in 2016's UFC 2 and the solo cover athlete in 2018's UFC 3. His last appearance in the series was in UFC 5 in 2023.

McGregor has had no scripted television cameos since 2024, appearing strictly as himself for promotional spots and interviews—including a guest appearance on The Tonight Show Starring Jimmy Fallon in June 2026. Fallon and NBC were heavily criticised for inviting McGregor onto the show. He is also attached to host and executive-produce a Fox Nation competition series titled World's Baddest Man, slated for 2027.
