The original target release date was December 21 , 2001 , in time for the 2001 Academy Awards but the production overshot that goal as Scorsese was still filming . A twenty-minute clip , billed as an " extended preview " , debuted at the 2002 Cannes Film Festival and was shown at a star-studded event at the Palais des Festivals et des Congrès with Scorsese , DiCaprio , Diaz and Weinstein in attendance
