Actor Emile Hirsch, best known for his starring role in Into The Wild, allegedly attacked and choked a female film executive at Sundance, according to Page Six. Its sources say a drunk Hirsch assaulted Paramount’s Dani Bernfeld at Tao Nightclub in Park City, where Hirsch is promoting his new film Ten Thousand Saints. The incident is said to have happened around 3:30 a.m. on Sunday when Hirsch—who “was aggressively picking on Dani”—became angry and proceeded to get “even more aggressive and aggro,” at which point he pushed Bernfeld against a table and put her in a “chokehold.” Police were called, though Hirsch wasn’t arrested. Page Six reports that he “calmly waited for the police to arrive, and spoke with them until around 5 a.m.”

Dani Bernfeld is the VP of Paramount Digital Entertainment and Insurge Pictures, and it’s unclear what, if anything, pushed Hirsch to attack her. Police are still investigating to decide whether charges will be filed.
