ET went behind the scenes of Office Christmas Party to see how far the raunchy holiday movie goes.

"People are giving themselves the excuse to hook up with the other coworkers, wear the most flashy outfits they have and to drink and debauchery is rampant," Olivia Munn tells ET. "This movie is every office Christmas party times 100."

In the movie, when a CEO (Jennifer Aniston) tries to close the branch run by her hard-partying brother (T.J. Miller), he and his Chief Technical Officer (Jason Bateman) rally their co-workers and host an epic office Christmas party in an effort to impress a potential client who could save their jobs.

While the purpose of the shindig is to keep the branch afloat, everyone uses the party to serve their own personal goals. Sam Richardson is a guy from legal, itching to show off his skills as a DJ, Vanessa Bayer is an executive assistant looking for love, and Kate McKinnon needs to satiate her obsession with the holidays.

"In my field I've never really been to an office Christmas party, so this is a whole new world for me," Aniston says.

The Golden Globe winner still found plenty to draw from. She told us that she based her character on the role she played in the '90s sitcom Ferris Bueller.

"Imagine Jeannie Bueller grown up -- that's Carol," Aniston says. "Sadly, she didn't develop her soft fuzzy side."

This marks Aniston's fifth film with Bateman after two Horrible Bosses movies, The Break-Up and The Switch, and McKinnon says they have enough funny material on the cutting room floor to add some more films to their catalogue.

"I think they could edit about eight movies out of the stuff they shot," says McKinnon.
