In the early 1960s, Stephen Sondheim outlined a musical stage adaptation and went so far as to compose the first scene with librettist Burt Shevelove. A chance encounter with Billy Wilder at a cocktail party gave Sondheim the opportunity to introduce himself and ask the original film's co-screenwriter and director his opinion of the project (which was to star Jeanette MacDonald). "You can't write a musical about "Sunset Boulevard"," Wilder responded, "it has to be an opera. After all, it's about a dethroned queen". Sondheim immediately aborted his plans. A few years later, when he was invited by Hal Prince to write the score for a film remake starring Angela Lansbury as a fading musical comedian rather than a silent film star, Sondheim declined, citing his conversation with Wilder.
