"Sunset Boulevard" is a musical with book and lyrics by Don Black and Christopher Hampton, and music by Andrew Lloyd Webber. Based on Billy Wilder's Academy Award-winning 1950 film of the same title, the plot revolves around Norma Desmond, a faded star of the silent screen era, living in the past in her decaying mansion on the fabled Los Angeles street. When young screenwriter Joe Gillis accidentally crosses her path, she sees in him an opportunity to make her return to the big screen. Romance and tragedy follow.

Opening first in London in 1993, the musical has had several long runs internationally and also enjoyed extensive tours.

The American premiere was at the Shubert Theatre in Century City, Los Angeles, California, on 9 December 1993, with Glenn Close as Norma and Alan Campbell as Joe. Featured were George Hearn as Max and Judy Kuhn as Betty. Lloyd Webber had reworked both the book and score, tightening the production, better organising the orchestrations, and adding the song "Every Movie's A Circus". This new production was better received by the critics and was an instant success, running for 369 performances.
