Gian-Carlo Coppola (September 17, 1963 – May 26, 1986) was an American film producer.
Coppola was killed in a speedboating accident on Memorial Day, 1986 at the age of 22 in Annapolis, Maryland. Griffin O'Neal, who was piloting the boat, had attempted to pass between two slow-moving boats, unaware that both boats were connected by a towline. While O'Neal barely had time to duck, Coppola was struck and killed. At the time of the incident, O'Neal was being directed by Francis Ford Coppola in Gardens of Stone and was subsequently replaced. O'Neal was later charged with manslaughter over the accident. He ultimately pleaded guilty to the lesser charge of "negligent operation of a boat", was fined $200 and sentenced to 18 months probation in 1987. He eventually received an 18-day jail sentence for not performing 400 hours of community service as ordered.
At the time of his death, Coppola's fiancee, Jacqui de la Fontaine, was two months pregnant with their only daughter, Gian-Carla "Gia" Coppola (born on January 1, 1987). Gia is a writer-director, having made the 2013 film Palo Alto.
Francis Ford Coppola subsequently dedicated 1988's Tucker: The Man and His Dream to his son. A scene in Francis Ford Coppola's 2011 film Twixt shows the death of a character as being similar to his son's death.
