Actually, no. The characters may be based on real people, with much of the dialogue culled directly from court transcripts, but Find Me Guilty plays the whole thing as comedy, and as everyone knows, putting an egomaniacal movie star in a bad hairpiece is comedy gold. Just ask William Shatner.
Diesel plays Jackie DiNorscio, depicted here as basically a lovable fuck-up, who describes himself as "a gagster, not a gangster" (this is the film's least funny line, and unfortunately it's repeated a few times, just to make sure you heard it). He's so amiable and so out of it that when his cousin Tony (Raùl Esparza) shoots him several times, he still loudly proclaims his love for the guy and refuses to identify him as the shooter to police. Left to his own devices afterward, Jackie is busted under the RICO anti-racketeering act, which, as he puts it, is used "whenever the government has no case." Still he ends up in jail, having inadvertently slept through his own trial while his elderly lawyer blew it.
Offered a reduced sentence by prosecutor Sean Kierney (Linus Roache) if he'll agree to testify against 19 other members of the Lucchese crime family, DiNorscio refuses, even though doing so will land him on trial alongside them, with the possibility of an extended sentence. But Jackie "ain't no rat," and besides, he figures that unlike the others, he's already in prison and can deal with it if he has to stay longer. That the rest of the family doesn't like him very much -- family head Nick Calabrese (Alex Rocco) threatens to cut Jackie's heart out if he so much as says his name aloud -- is never an issue.
Disillusioned with his previous lawyer, Jackie decides to represent himself. Warned by the judge (Ron Silver) that the man who does so is said to have a fool for a client, Jackie asks, "Is dat true?"
"Sometimes it is," replies the judge.
"Dat means sometimes it ain't, though, right?"
In this instance, right he is. Jackie's clumsily amusing antics proceed to charm the jury and irritate the judge and lawyers. Most likely they'll charm audiences too, though the movie, based as it is on a trial of record-setting duration, occasionally wears out its welcome by going similarly long. At over two hours, it could use some trimming, especially of the scenes that take place outside the courtroom.
Lumet as a director is probably never going to be as good again as he was in the '70s (Network, Dog Day Afternoon, Serpico), but his work here with the actors is strong -- particularly with Peter Dinklage, as an overly mannered defense attorney; Roache, who hams it up dramatically; and Silver, giving his best performance in a long time.
Diesel has made so many bad movies lately, it's easy to forget that he does have talent. Here, he reminds us all, while cannily stepping away from the rote-action shtick that made him boring.
