The actor attacked a female Hollywood executive, Daniele Bernfeld, at the Sundance Film Festival bash last month in Utah.
The actor was drunk when he confronted the movie exec at the film festival.
Hirsch reportedly asked [Daniele] why she looked “so tough”, telling her she was “a rich kid” who shouldn’t be at Sundance.
The incident occurred around 3:52 p.m. on January 25 at Tao Nightclub in Park City, Utah.
Bernfeld claims the 29-year-old Into the Wild star pulled her across a table and onto the floor where he landed on top of her.
The police report states that he then put his hands around her neck and choked her so hard that she felt “the front and back of her throat were touching”.
Bernfeld told police everything went dark and she blacked out for a moment.
Summit County prosecutor Ryan Stack confirmed that the woman, Dani Bernfeld, is an executive for Insurge Pictures, which is a subsidiary of Paramount Pictures.
The Into the Wild actor was charged with third degree felony aggravated assault on Thursday and misdemeanor intoxication.
The 29-year-old actor has now checked into rehab.
Hirsch’s spokesman Robert Offer stated, “Emile consumed an enormous amount of alcohol on the evening in question and he has no memory of what happened. 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.”
Hirsch is due back in court on March 16.
