This Could Be the Night (1957)

"This Could be the Night" is a charming fish-out-of-water story about a straight-laced girl who becomes a part-time secretary at a seedy nightclub in New York. Jean Simmons plays Anne, the self-possessed college grad who's trying to expand her horizons by taking a job where she's surrounded by "characters." The club staff quickly find out that she's a "nice girl" -- that is, a virgin -- and tacitly conspire to keep her that way. No-one takes this task more seriously than Tony, one of the owners, and a well-known lothario. Naturally he's falling for her and is determined to keep her out of every man's clutches, especially his own.

The chemistry between Simmons and Fransciosa sizzles and all the characters' tiptoeing around the word "virgin" definitely gives the movie more sexual overtones than you would expect. The club staff are a likeable bunch -- from busboy Hassan, whose father won't let him change his name until he passes algebra, to strip-dancer Patsy, who really wants to be a cook. The dialogue is snappy and intelligent and the characters stay true to the end.
