Actor Emile Hirsch does not remember allegedly choking a studio executive and dragging her across a nightclub table because he was so drunk, his lawyer has said.
The Into The Wild star checked into rehab within days of the incident and is still there, his entertainment lawyer Robert Offer said in a statement .
"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," Mr Offer wrote.
"However, Emile takes these allegations very seriously, and is devastated that any of this has occurred."
The 29-year-old actor was charged in Utah with felony aggravated assault over an incident in which a studio executive accused him of putting her in a headlock and dragging her across a table in late January.
"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," Mr Offer wrote. "Emile is continuing to co-operate fully with authorities."
Hirsch is accused of attacking Daniele Bernfeld, an executive at Insurge Pictures, a subsidiary of Paramount Pictures, during the Sundance Film Festival in Park City, Utah.
Court documents say the incident happened on January 25, when Hirsch, looking drunk, approached Ms Bernfeld and asked why she looked "so tough". He also said she was a "rich kid who should not be at Sundance".
Investigators say Hirsch grabbed Ms Bernfeld and she pushed him away. He left and sat with friends before coming back and grabbed her from behind, the documents say.
She was put in a chokehold and pulled across the table before Hirsch landed on top of her on the floor, authorities said.
Ms Bernfeld said she saw things going dark and might have blacked out momentarily.
Hirsch, who will make his first court appearance on March 16, faces a misdemeanour count of intoxication.
