TORONTO, Ont. -- Sometimes in a smaller theater, away from the searchlights and the 24-hour fans making privacy impossible for poor Brad and Angelina, you find an independent film that is miraculous. Such a film is “Chop Shop,” by Ramin Bahrani, the Iran-born American director whose “Man Push Cart” made such a stir three years ago. That film was about an immigrant from Pakistan trying to make a living in New York with a rented coffee-and-bagel cart. It was shot on a shoestring in less than three weeks, and won the critics’ prize at London and three Independent Spirit Awards, including best first feature. It embodied, I said in my review, the very soul of Italian neorealism.
