Platinum is a musical with a book by Will Holt and Bruce Vilanch, music by Gary William Friedman, and lyrics by Holt. Set in a Hollywood recording studio, it centers on Lila Halliday, a star of 1940s and 50s movie musicals who is attempting a comeback as a rock singer.

Platinum was originally titled Sunset when it made its world premiere in 1977 at the Studio Arena Theatre in Buffalo, New York. The production, with a book by Louis LaRusso II, was directed by Tommy Tune. When the musical evolved into Platinum and moved to Broadway, only the songwriters, Alexis Smith, Lisa Mordente, and ensemble member Christine Faith remained with the production. (A revised version of the original Sunset was presented off-Broadway at the Village Gate in 1983. Starring Tammy Grimes, it closed after one performance.)
