A musical prodigy accepted to Juilliard at age six, Hamlisch defied classical expectations to create his own music, dedicating his talents to musical theatre and pop music composition. By age 31, he achieved unprecedented success and honors with a string of SMASH hits, and then his streak ended. Faced with overwhelming pressure and sky-high expectations to repeat his hits, Hamlisch fell into a self-described "period of suffocating despair," before rebounding to find true love worthy of a Broadway musical and renewed passion for creation. American MastersMarvin Hamlisch: What He Did For Love reveals the events that led to both his staggering success and, ultimately, his even greater humanity: his creative process, struggles, inner turmoil, and breakthroughs.

Composer, conductor, genius, mensch: Marvin Hamlisch (June 2, 1944 - Aug. 6, 2012) earned four Grammys, four Emmys, three Oscars, three Golden Globes, a Tony Award, and a Pulitzer Prize before his untimely death, making him one of only two PEGOT winners ever. Hit after hit -- "The Way We Were," "Nobody Does It Better" and scores for The Sting, Sophie's Choice and the Broadway juggernaut A Chorus Line -- made him the go-to composer and performer for film, Broadway, every U.S. President since Reagan, and concert halls worldwide.
