Sonny Boy (Italian: Il dono del silenzio) is a 1989 black comedy-drama thriller film directed by Robert Martin Carroll.
It stars Paul L. Smith, David Carradine, Brad Dourif, Conrad Janis, Sydney Lassick, Alexandra Powers, and Steve Carlisle.
In 1970, Harmony, a small town in New Mexico, is run by a small-time crime boss named Slue, who accepts the delivery of a Lincoln Continental car stolen by his henchmen Weasel, who brings it after killing a couple who was travelling with their child.
When the grown Sonny Boy escapes and tries to make contact with the outside world, the attention he draws to his warped family results in darkly-humored mayhem.
The first verse from the Sonny Boy theme, "Paint" (which he wrote while filming Americana in Drury, Kansas, in 1973), is engraved on his headstone, as an epitaph.
