Barnes knew he'd be scooped up into the ever-growing Marvel Cinematic Universe, eventually. "There was certainly a period a few years ago where young, British actors were playing Batman and Superman and Spider-Man and I thought, 'Guys, could you just please leave one for me somewhere?!'" Barnes, a fellow Brit, recalls, referring to Christian Bale, Henry Cavill and, most recently, Tom Holland. He'd been called in before by Marvel regarding another character from the Daredevil universe ("I can't remember which one it was"), but it was never the right fit until The Punisher. "Inevitably, it is never even vaguely what you think it's going to be."
In The Punisher, Barnes plays Billy Russo, an old Special Forces comrade of Frank's who goes on to found Anvril, a corrupt, weapons-dealing military complex. It's a character that debuted in The Amazing Spider-Man comics before becoming the arch-enemy of The Punisher, a deformed supervillain known as Jigsaw. "Nobody has said that name still to me from Netflix or Marvel," Barnes says, though when I suggest that he missed out on the facial prosthetics required of Jigsaw's mutilated face, he demurs, "Well, I didn't say that I missed out on them, necessarily."
