Stephen Leo Bing (born March 31, 1965) is an American real estate developer, film producer, and donor to progressive causes.
At the age of 18, Bing inherited an estimated $600 million from his grandfather, Leo S. Bing, who had made his fortune in New York real estate in the 1920s. The Los Angeles Business Journal in May 2006 estimated his family's worth at $900 million, coming in at No. 42 in that publication's list of Wealthiest Angelenos: L.A.'s 50 Richest
Bing attended the elite Los Angeles Harvard-Westlake private school. Before graduation, he'd written (with veteran sitcom writer Arthur Silver) his first screenplay, "Missing in Action." It became a Chuck Norris film that had a sequel.
