IFC Films Mike Birbiglia in 'Sleepwalk With Me.'

Why He's On Our Radar: Mike Birbiglia came to Park City this year as a popular comic and emerged as an acclaimed filmmaker, writer and actor following the great reception his film debut, "Sleepwalk With Me," received at Sundance. The film won the Best of NEXT Audience Award (beating out Craig Zobel's button-pushing "Compliance") and found a home at IFC Films.

The comedy -- co-written by Joe Birbiglia, Seth Barrish and "This American Life" host Ira Glass -- is a semi-autobiographical tale based closely on Birbiglia's popular off-Broadway show of the same name. It centers on a struggling comedian (Birbiglia), whose growing anxieties about settling down with his girlfriend (Lauren Ambrose) take the form of vivid dreams that cause him to sleepwalk. The film opens at New York's IFC Center Friday, August 24, and expands throughout the country the following week.

What's Next: Birbiglia isn't messing around with the formula that brought him praise and indie-film cred. He told us that he's in the process of adapting his latest solo play "My Girlfriend's Boyfriend" into a sophomore feature. The show, which explores Birbiglia's bumbling love life, ended its successful off-Broadway run March 18, 2011 and is currently touring the States after playing around the world.

"It's about how I basically decided to get married without believing in the idea of marriage," he told Indiewire about his latest screenplay. "It's about giving up on the idea of being right on things."

Whereas "Sleepwalk With Me" is a largely autobiographical tale like the play that inspired it, Birbiglia is doing things differently for his follow-up. "I've done a draft of it, and in it the character's not autobiographical," he said. "In the play he's a comedian, and in the film he's a journalist. There are definitely ways that it eases away from autobiography. I just like when you look at people who have long careers in film, they're able to make films that are far away from themselves, because they're metaphorical. It creates more opportunities, I think."

So, first things first. I've been actively following this feud between you and Joss Whedon. Have you two made peace?

Joss is going to be Joss, and we're going to be us. We will defeat him. I think there are some people who don't understand how we'll do it, but we have a secret plan.

How did that whole thing come to be?

Ira. Ira had him on a "This American Life" live event years ago, which I was on. He did a song from "Dr. Horrible" and I did a story.

"I didn't want to become this kind of Lifetime memoirist."

What gave you the impetus to adapt "Sleepwalk With Me" for the screen?

I was working on another screenplay at that point and it had a lot of similar themes. It was called "Waking Up Ben." It was about a guy sleeping through his life. I was writing that and people kept telling me I should just adapt "Sleepwalk With Me" for the screen. But I thought it felt too personal. I didn't want to become this kind of Lifetime memoirist. But at a certain point I was like, why not give it a try? I thought there were elements that would work. Dreams work cinematically, and I thought sleepwalking would work too, visually. Once I started on the journey, there were so many things about it that worked cinematically that I just pushed on through.

I was surprised to learn in reading a first-person story you wrote for us prior to Sundance that you had always wanted to make a feature film, even before striking it big as a comic.

That's what I wanted to do. I couldn't afford it. It was part of my five-year plan, it just took 14 to happen. I was like, I'm going to become a comedian, it's going to go well, then I'm going to write a film with that comedian persona. It just took forever. I'm 34 now!
