Seth [Rogen] had written a script with this guy, Evan [Goldberg], who none of us knew, and he was prepared to move to L.A. to try to get a script made. It had no title. I actually gave them the suggestion of naming it Superbad, which they did. I just thought it was a weird, interesting name for it. Evan came to L.A. to live with Seth, to be his roommate. It was kind of like, "Who's the new guy?" Within days, we all loved Evan. Long story short, both of them were groomsmen at my wedding.

We [me and Seth Rogen] have always wanted to work together. That was the whole point. We talked about it actively, and then we finally got the opportunity to do that, over and over again. It's kind of a dream come true.

The only lesson I really learned from [Gigi Does It] was that I shouldn't bite off more than I could chew. I've written a bunch of scripts and stuff - every actor has - and that was the first thing that got made.

I was doing a Broadway play, and I was really new to this business. The Broadway play was my first job, literally. The play next door was a musical called Falsettos. The director got hired to direct this Michael J. Fox movie and was looking for a kid who could play brash and salty and mean [in Life With Mikey].

What's great is that because math is such a universal language, really, our fans come in all shapes and sizes, all ages and genders and races and backgrounds and cultures.

To go to L.A. and be on the Addams Family set? It was beautiful production design and an illustrious set. I'm focused on never losing that sense of privilege. I'm still like, "I'm super lucky."

In fact, one of the funny stories from that set [of Hail, Caesar!] is we were shooting my scene, and around lunchtime, Terrence Malick shows up on set. He was uninvited and no one knew who he was. But I knew, just looking at him. I was like, "Holy moley, that's Terrence Malick!" So I went and told the PA, "Hey, Terrence Malick is here, and I think he wants to see the Coen brothers. He wants to talk to Joel and Ethan." He just showed up unannounced, uninvited, and I guess they spent their lunch hour with him.
