Directed by Tony Award-winner and frequent Sondheim collaborator James Lapine, SIX BY SONDHEIM is a highly personal profile of a great American artist as revealed through the creation and performance of six of his iconic songs. Told primarily in Sondheim's own words, this feature documentary weaves together dozens of interviews with the composer, rarely seen archival material spanning more than half a century (including newly discovered footage of Ethel Merman performing "Gypsy�) and re-stagings of three songs produced especially for the film.
