Once's Cristin Milioti on Her 'Incredible' New Movie Sleepwalk with Me and Prepping to Play Leonardo DiCaprio's Ex

Tony-nominated Once star Cristin Milioti is among the ensemble cast of Mike Birbiglia’s Sleepwalk with Me, the new film adaptation of his 2008 off-Broadway one-man show, and the actress has nothing but praise for the comedian.

“He is the shit!” Milioti joked with Broadway.com recently. “I told him that at a party once. He’s made a really incredible movie.”

The film follows Matt (Birbiglia), a comedian who, as his relationship with his girlfriend of eight years begins to go south, develops a bizarre habit of sleepwalking. Milioti plays his sister, whose new engagement adds pressure on Matt to get his life together and settle down. “He can write, he can act, he can direct,” Milioti continued to rave about Birbiglia. “He’s a great guy. Everyone in the film is so wonderful and it was a wonderful thing to be a part of.”

Milioti will return to the big screen soon as she recently landed a role in Martin Scorsese’s next film The Wolf of Wall Street. Based on a true story, the film stars Leonardo DiCaprio as Jordan Belfort, a Wall Street tycoon known for living an extravagant lifestyle until he lands in jail for illegal stock market practices. “I’m very excited,” she said of the project, which begins filming this week. “I’m beside myself excited!”

Milioti remained mum on details of her involvement with the film, but noted, “I play [Belfort’s] first wife and that’s pretty much all I can say. There is some tension there, but it’s really good." Scorsese and DiCaprio have collaborated on four previous films together including The Departed and The Aviator. So is Milioti nervous to work with the prolific duo? “They are so lovely,” she said. “I’ve met them and they’re so sweet. They’ve done this a couple times, so I feel like I’m in good hands.”

Sleepwalk with Me hits theaters August 24. Click below for the film’s trailer, and be sure to catch Milioti in Once at Broadway’s Jacobs Theatre.
