At the Mission: Impossible — Fallout press junket, we asked Henry Cavill which big bad he’d most like Superman to fight that he hasn’t faced off against yet. He told us exclusively: “I think a great villain would be Brainiac. I think that would be a good villain to play against. Brainiac is a big threat. He’s a lot of fun. There’s a lot to him, there’s a lot of storylines to him.”
