Film actor Emile Hirsch has been charged by Utah authorities with third-degree felony aggravated assault and class C misdemeanor intoxication for allegedly choking a studio executive at a Park City nightclub during the Sundance Film Festival.

Hirsch, 29, does not remember events of the night because he was drunk, his attorney wrote in a statement.

The actor checked into rehab within days of the incident and remains in treatment, attorney Robert Offer wrote in a statement obtained Friday.

Hirsch, whose address is listed as Encino, Calif., has been summoned to appear in Summit County's 3rd District Court on March 16.

Aggravated assault is punishable by up to five years in prison.

"Regarding the charges that have been brought against Emile Hirsch today, the facts that I can relay are that he consumed an enormous amount of alcohol on the evening in question and he doesn't have any memory of what happened at the time of the allegations," Offer wrote. "However, Emile takes these allegations very seriously, and is devastated that any of this has occurred."

According to charging documents, the alleged victim was at TAO, a temporary nightclub, at about 4 a.m. on Jan. 25, when Hirsch — who reportedly appeared to be intoxicated — approached and asked why she looked "so tough" and said she was a "rich kid" who should not be at Sundance.

The woman — a Paramount executive — pushed Hirsch away and sat down at a table to talk with a friend, court documents state.

Soon after, Hirsch came up behind the woman and put her in a chokehold, pulling her across the table and onto the floor, where he landed on top of her, charges state.

While Hirsch was on top of the woman, he wrapped his hands around her neck, charges state.

The woman told police she may have blacked out momentarily before two bystanders pulled Hirsch off of her.

A witness who was sitting next to the woman corroborated her statement, charges state. The witness told police that the woman was shaking and crying and that she said, "The front of my throat hit the back of my throat ... I couldn't breathe."

A police officer observed redness on the woman's neck and upper chest, charges state.

Hirsch later told police that he did not know the woman, but was in a "verbal confrontation" with her. He said he had consumed three or four alcoholic drinks, charges state.

A police officer observed that Hirsch's eyes were red and glossy, he had an odor of alcohol coming from his mouth, his balance was poor and he slurred some of his words, charges state.

"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," Offer wrote. "Emile is continuing to cooperate fully with authorities."

Hirsch was in a movie that premiered at Sundance called "Ten Thousand Saints."

The film is about a Vermont teen (Asa Butterfield) who, after his friend overdoses, is sent to live with his father (Ethan Hawke) in Manhattan — where he befriends his friend's pregnant girlfriend (Hailee Steinfeld) and his straight-edge half-brother (Emile Hirsch). Hirsch also has appeared in the movies "Into The Wild" and "The Girl Next Door."

Offer is Hirsch's entertainment lawyer. The actor is being represented in the criminal case by Utah attorney Neil Kaplan and Los Angeles attorney Blair Berk.
