Oliver Stone may be a Hollywood success story, but the Academy Award-winning helmer hasn’t forgotten his training roots.

“Directors may scale to great heights … and actors may wither and die, but film schools will always last,” said Stone, the man of honor at the Los Angeles Film School’s official ground-breaking ceremony in Hollywood last week.

After cutting the red ribbon outside the tech-focused learning facility (once home of RCA headquarters) Stone continued, “As a tortured grad of NYU, I’m proud to dedicate today the Los Angeles Film School.”

Stone did warn biz hopefuls that “it’s a terrible business to get into and more fail than succeed.” However, “there’s always a lunatic ready to jump off a building to get into it.”

A fitting comment, considering the event ended with a professional stunt team free-falling off the school’s roof.

Adding to the opening-day hype, Producers Guild of America prexy and the film school’s managing partner Thom Mount plugged, “We’re the only one-year professional craft school in the area … and have the country’s first high-definition training facility.”

Mount also pointed out that Stone will join the school’s advisory board, which already includes director Amy Heckerling and Oscar-winning cinematographer Janusz Kaminski.

Classes officially start Sept. 8, but enrollment applications are accepted year-round.

Others attending the festivities included city of Los Angeles cultural affairs director Adolfo Nodal; the school’s prexy, Carolyn Pfeiffer; co-founder Bud Malette; and its dean, Amedeo D’Amato.
