Film director Tony Scott*68-year-old director Tony Scott, who took his own life Sunday by jumping off the Vincent Thomas bridge in Los Angeles harbor, may have been battling brain cancer.

Ed Winter, the assistant chief coroner for Los Angeles County told the Daily News a brain issue could be determined by the autopsy, scheduled for some time today, Monday.

Investigators found a note in Scott’s black Toyota Prius, which was parked on the bridge, according to the Los Angeles Times. That note listed contact information. A suicide note was later found at his office.

The British-born Scott, who lived in Beverly Hills, was producer and director Ridley Scott’s younger brother. Distinct visual styles mark both siblings’ films — Ridley Scott mastering the creation of entire worlds with such films as “Gladiator,” “Blade Runner,” “Alien” and this year’s “Prometheus,” Tony Scott known for hyper-kinetic action and editing on such films as his most recent, the runaway train thriller “Unstoppable,” starring regular collaborator Denzel Washington.

Scott was a thrill-seeker himself in his personal life, an avid rock climber who also liked driving fast cars and motorcycles. Still, filmmaking was his real thrill.

“The biggest edge I live on is directing. That’s the most scary, dangerous thing you can do in your life,” Scott said in an interview for his 1995 naval adventure “Crimson Tide” that starred Washington. “The scariest thing in my life is the first morning of production on all my movies. It’s the fear of failing, the loss of face and a sense of guilt that everybody puts their faith in you and not coming through.”
