VAUGHN: When you rang me up and said that you were having a baby, I felt like it should have shocked me more than it did. I find it intriguing that I wasn’t that surprised.

JOHNSON: Mmm. [laughs] Well, it would shock me if Chris [Mintz-Plasse, Johnson’s co-star in Kick-Ass] phoned me up and said he’s having a baby. He wouldn’t have a clue what to do.

VAUGHN: I still don’t even have a clue how to make one. You’ve been acting since you were quite young. How do you think you escaped becoming a child actor from hell? Because a lot of kids who’ve been acting since they were 5 or 6 normally turn into really crap actors.

JOHNSON: You’re probably thinking of a lot of American actors there.

VAUGHN: Yeah.

JOHNSON: Or Hollywood actors. I was brought up by a really proud, supportive family, so I have that sort of grounding. When I was about 10, I went off to film a movie in Amsterdam…

Knowing that I actually just want to be at home for a little while to see Sam’s belly grow, I’ve said no to some things. But the more I’ve said no, the better things have come alongAaron Johnson

VAUGHN: What were you filming in Amsterdam?

JOHNSON: Some film that goes on Sky Movies. It was the first film I ever did. It was called Tom & Thomas [2002]. I played twins who get split up at birth—one goes to an orphanage or something, and the other lives in this beautiful home. But, you know, it was all made with Dutch money, and it basically went nowhere apart from Sky Movies—they quite liked it as a family film to show around Christmastime at nine in the morning. But I was brought up in a village outside of London, and no one really knew what I was doing when I’d go away for that amount of time—and I’d never talk about it. I was never that kid who used to brag about anything.

VAUGHN: How are you going to pick your next movie?

JOHNSON: Wisely. Knowing that I actually just want to be at home for a little while to see Sam’s belly grow, I’ve said no to some things. But the more I’ve said no, the better things have come along.

VAUGHN: I told you to do that, didn’t I?

JOHNSON: Yeah, you did say that. But it’s kind of funny, though, because I’ve never even thought of being in that sort of a position.

VAUGHN: In Hollywood, the power of no is huge. Is there any type of genre you want to try next?
