 The soggy weather played havoc with the shooting of the wedding  dress dance scene. Fred Astaire (qv) and Audrey Hepburn (qv)  were continually slipping in the muddy and slippery grass. Hepburn  sings several songs. Her next full musical,  _My Fair Lady (1964)_ (qv), would see her voice overdubbed, much to  her disappointment.
