Steve Bing, the film financier and philanthropist who backed hit movies from Robert Zemeckis’ The Polar Express and Beowulf to the Rolling Stones’ Shine A Light concert movie, has died.

According to law enforcement sources, Bing leapt off a Century City, CA building at around 1 PM Monday.

Bing was also an influential political donor, and in 2012 pledged a $30 million legacy gift to the Motion Picture & Television Fund.

“For years Steve Bing has been one of the most philanthropic and generous people in our industry,” Jeffrey Katzenberg said at the time. “He has also been one of the most loyal supporters of the MPTF through both the good and challenging times. Now with this amazing contribution he puts us another step closer to securing our long-term goals.”
