Fassbender read the part of The Dude (originally played by Jeff Bridges), while Lawrence took on Julianne Moore’s role as Maude. Munn played Bunny, Maude’s stepmother, Mashable reports, while Oswalt was John Goodman’s Walter.
At the event, which was part of the Just For Laughs festival, Fassbender dressed for the occasion — wearing The Dude’s signature bathrobe. He also reportedly smoked cigarettes on stage and drank a cocktail during the reading.
“I think Fassbender went a little too Method on this one. I hope TMZ isn’t here,” Oswalt joked, according to Variety.
