Tony Award-winning Broadway producer Dori Berinstein ("Carol Channing: Larger Than Life," "Show Business: The Road To Broadway") directed, wrote and produced the documentary about Hamlisch, whose numerous accomplishments included the Tony and Pulitzer Prize-winning musical A Chorus Line. It premiered Dec. 27 on PBS.
"What He Did for Love," according to PBS, "reveals the events that led to both his staggering success and, ultimately, his even greater humanity: his creative process, struggles, inner turmoil, and breakthroughs."
The documentary features Barbra Streisand, Woody Allen, Tim Rice, Idina Menzel, Carole Bayer Sager, Steven Soderbergh, Quincy Jones, Christopher Walken, Joe Torre, John Lithgow, Lucie Arnaz, Ann-Margret, Howard Stringer, Kelli O'Hara, Brian D'Arcy James, Melissa Manchester and Hamlisch's wife, Terre Blair Hamlisch.
It has also been revealed Bernstein was collaborating on a new musical with Hamlisch prior to his death. She is working to finish the musical, which will feature his final score.
