Find Me Guilty is a 2006 American courtroom comedy-drama crime film co-written and directed by Sidney Lumet, based on the true story of the longest Mafia trial in American history. The film stars Vin Diesel as mobster Giacomo "Jackie" DiNorscio, who faces a series of charges even though he has a prior 30-year conviction, but he decides to stand trial instead of ratting out his family and associates.
