Publicist Susan Patricola said Friday that the 30-year-old Hartnett was released earlier this week after undergoing tests to determine the cause. He had been transported Monday to Cedars-Sinai Medical Center.
Patricola says Hartnett had a flare-up of a gastrointestinal issue last year that affected him while he was starring in an onstage production of "Rain Man" in London.
Hartnett has appeared in the films "Black Hawk Down," "Sin City," "40 Days and 40 Nights" and "The Black Dahlia."
