“Ant-Man and the Wasp, we’re a team,” Mr. Rudd said. “She is, in the first film, somebody who I think was probably so much better suited for the job than I was and finally has been given the wherewithal to be who she was born to be, which is a badass and the rightful heir to the throne.”

Natty in a crisp summer suit at an Argentine bistro in TriBeCa, just around the corner from where he lives with his wife, Julie, and their children, Jack, 13, and Darby, 8, Mr. Rudd, 49, talked about his midlife foray into superherodom, the spoils of fame and the burden of being so darn likable.

Here are edited excerpts from the conversation.

I’ve read that you don’t like the interview process.

I’ll be honest with you: I never feel totally comfortable talking about myself in this kind of setting, and there’s always some kind of filter. I’ve done it for so many years now that I wonder if my own narrative is even true anymore or if I’m just going off of answers I’ve given in interviews. Like, is that really how it started? Is this really how I feel about things or is that because I answered this question once and now it has become true? No, I don’t love it but it really is part of the gig, isn’t it?

It is when you’re a superhero. Or do you prefer the term action figure?

I call myself an action figure in real life and a superhero in fake life.

What’s it like moving into that realm at what we might call the midpoint of your career?

I hope not. If it is, we’ve just predicted my death. [Laughing] I was very excited by it. It was so out of left field and something so different than anything I’ve done, and I thought this would be the first thing that my kids would be able to watch.
