The actor was charged with aggravated assault, which is punishable by up to five years in prison and a $5,000 fine. He is also facing a misdemeanor count of intoxication.
Summit County prosecutor Ryan Stack confirmed that the woman, Daniele Bernfeld, is an executive for Insurge Pictures, a Paramount Pictures subsidiary.
Court documents say the altercation occurred Jan. 25 at Tao Nightclub in Park City, when Hirsch, looking drunk, approached Bernfeld and asked why she looked "so tough."
He also said she was a "rich kid who should not be at Sundance," the documents say.
Investigators say Hirsch grabbed Bernfeld and she pushed him away. He left and sat with friends before coming back and grabbing the woman from behind, the documents state.
She was put in a chokehold and pulled across the table before Hirsch landed on top of her on the floor, authorities said.
Bernfeld told authorities she saw things going dark and might have blacked out momentarily.
Hirsch, 29, of Encino, California, told police he didn't know Bernfeld but was having an argument with her.
He said he had three to four drinks. An officer reported to prosecutors that the actor's balance was off, he was slurring his words and smelled of alcohol.
Hirsch is best known for his starring role in "Into the Wild." He also appeared in Universal's Navy SEAL drama "Lone Survivor," Peter Berg's account of a disastrous 2005 military operation in Afghanistan.
His agent Brian Swardstrom and attorney Robert Offer didn't immediately return messages Thursday seeking comment. Neil Kaplan, a Utah attorney listed for Hirsch in online court records, also didn't immediately return messages seeking comment.
Hirsch was not arrested and was scheduled to make his first court appearance March 16 at a court in Park City. Stack said the filing of charges came two weeks after the altercation because time was needed to secure key information. He did not elaborate.
Hirsch's spokesperson, Robert Offer, told TMZ the actor checked into rehab after the incident.
"Emile consumed an enormous amount of alcohol on the evening in question and he has no memory of what happened." Offer said, according to the website. "Emile takes these allegations very seriously, and is devastated that any of this has occurred. A few days after the incident, Emile sought help and checked himself into an alcohol rehabilitation facility, where he remains today, to ensure nothing like this ever happens again."
Efforts to reach Bernfeld and her employer were not successful. Insurge Pictures distributed the Ben Stiller-produced web comedy "Burning Love," which was also on the E! network.
Hirsch was at Sundance for the premiere of the drama "Ten Thousand Saints," a movie in which he appears alongside Ethan Hawke and Asa Butterfield.
