LOS ANGELES — Actor Emile Hirsch, 29, does not remember events of the night he is accused of attacking a studio executive because he was drunk, his attorney said.

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

“He consumed an enormous amount of alcohol on the evening in question and he doesn’t have any memory of what happened …,” Offer wrote.

The “Into the Wild” actor was charged in Utah on Thursday with the felony aggravated assault of a studio executive in late January.
