"She's a demon, period," McAvoy joked to the mag. "She can throw a punch, she's got a good shot, she can drink. She's proper. I like that girl."
McAvoy also bragged about working with Angelina Jolie on their 2008 movie Wanted.
"It is amazing, seriously, and I am thrilled about it," he dished. "I kissed f--king Angelina Jolie. Yes, we had a bit of a snog."
As for how Brad Pitt feels about their snogging, McAvoy added, "I am sure he's deeply unthreatened, deeply unmoved, and probably reassured in his masculinity. Probably."
"I was taking a piss," he admitted. "And I did have a sneaky vodka tonic. But I got totally caught out, because I was thinking that category was going to be way down the line. And then, of course, you can't get back in until it's a commercial break, so I watched it backstage. I felt pretty embarrassed about that...So there's a stand-in beside my mom. And Brad Pitt said he could hear them going, ‘Michael Fassbender? Where's Michael Fassbender?' Bad timing on my part."
