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 Jackie DiNorscio, who faces a series of charges even though he has a prior 30-year sentence, but he decides to stand trial instead of informing against his family and associates. A wrench is thrown into the system when DiNorscio attempts to defend himself and act as his own lawyer at trial.
