Ms. Rosenthal, who had already spent 10 years in Los Angeles working for studios such as Universal and Walt Disney, to return to New York City. In August 1988 they founded Tribeca Productions to develop projects for Mr. DeNiro to act in, produce and direct. As well as scouting film projects, Ms. Rosenthal does day-to-day management of Mr. DeNiro's Tribeca Film Center, which rents space to filmmakers and aims to provide an artistic community for them. Ms. Rosenthal's career reads like a movie script. As an enterprising New York University film student, she landed a job at the CBS network. At the same time, she produced the workshop for The Best Little Whorehouse in Texas at the Actors Studio. She so impressed CBS that at the ripe age of 21, she went to Los Angeles as CBS director of motion pictures for television, making her the highest-ranking, youngest woman network executive. While working on Walt Disney's The Color of Money, she met director Martin Scorsese. He recommended her to Mr. DeNiro.
