Mannequin is a 1987 American romantic comedy fantasy film starring Andrew McCarthy, Kim Cattrall, Meshach Taylor, James Spader, G. W. Bailey, and Estelle Getty.  Directed and written by Michael Gottlieb, the film was also co-written by Edward Rugoff.  The original music score was composed by Sylvester Levay.  The film, a modern re-telling of the Pygmalion myth, tells about a chronically underemployed artist named Jonathan Switcher (played by Andrew McCarthy) who gets a job as a department-store window dresser and falls in love with a mannequin (played by Kim Cattrall)—the attraction being that she comes to life on occasion, but only for him. "Nothing Can Stop Us" is the third single by Saint Etienne.  Released by Heavenly Records in 1991, it is the first release to feature Sarah Cracknell, who would continue to front the band from this release on.  "Nothing Can Stop Us" reached the number one spot on the American dance charts for one week.  The song is based on a looped sample from Dusty Springfield's recording of "I Can't Wait Until I See My Baby's Face".
