Aubrey Plaza Makes Bill Murray Sex Joke, Talks 'A Glimpse Inside The Mind Of Charles Swan III' (VIDEO)

Aubrey Plaza was at the Sundance Film Festival to promote her new sci-fi romance, "Safety Not Guaranteed," but she also spent some time talking about her role in the upcoming comedy "A Glimpse Inside The Mind Of Charles Swan III."

"It's pretty delicious," she said of the comedy, directed by Roman Coppola, about a man who experiences fever dreams of past relationships as he goes through an emotional breakdown and tries to turn his life around.

"You've got Charlie Sheen being crazy, Bill Murray is in it, Jason Schwartzman is playing a standup comedian," she said. "He has, like, a full beard and he's amazing. It's a really, really playful, fun movie set... in a fantasy version of the 70s."

Plaza went on to praise Coppola's vision -- and Murray's prowess.

"We had an experience that, in nine months, the world will be a part of," the "Parks and Recreation" actress deadpanned.

This isn't the first time she's made headlines with a joke involving another celebrity at this year's Sundance; earlier this week, Plaza joked to Vulture that she would "maybe murder" Ryan Gosling's girlfriend so that she could be with the "Drive" star.
