Although there is little detail about how the confrontation started, and eye witness told Page Six, "Something happened between the movie exec and Emile, and she said she had been assaulted and asked security to call the police. Emile didn't leave the scene, and calmly waited for the police to arrive, and spoke with them until around 5 a.m., after which he went home with his friends. No arrests were made."

It is understood that the film exec didn't press charges at the scene, but another source told Us Weekly, "Last night, Emile Hirsch got into a fight with an executive at Paramount at TAO Sundance, and the executive was looking into pressing charges against Emile this morning."
