You'll find this thread from last year to be of interest. From one of my posts in that thread:

"The Umbrellas of Cherbourg" -- directed by Jacques Demy; music by Michel Legrand.
"Marry Me! Marry Me!" -- directed by Claude Berri; music by Emil Stern.
Both are 1960s French films. "The Umbrellas of Cherbourg" is pretty much unique among non-operatic films in that all of its dialogue is sung, not spoken, and it is also exceptional in terms of its use of color.
Also:
"2001: A Space Odyssey"
"My Fair Lady"
"West Side Story"
