A studio executive who authorities say was assaulted by actor Emile Hirsch during the Sundance Film Festival earlier this year described the incident as being “insanely painful and absolutely terrifying,” according to public records obtained by The Associated Press. Daniele Bernfeld, an executive for the Paramount Pictures subsidiary Insurge Pictures, told police that Hirsch put her in a chokehold from behind, dragged her across a table and body slammed her to the floor, investigative documents obtained Thursday through a public records request showed.
