Seven Year Itch (1955)

The Seven Year Itch (1955) - Directed by Billy Wilder
Story about a man who finds himself in a tempting situation with a young woman while his wife is away on vacation. Features the classic scene where Marilyn's skirt is blown upwards by a gust of wind from a grating.
Ewell's crack timing is matched by Monroe's zesty comic flair, and the scene in which her white dress is blown skyward by a passing subway train has entered the encyclopaedia of great movie images.
