|The Moon Is Blue: Successful architect Don Gresham (William Holden) engages a young actress, Patty O'Neill (Maggie McNamara), in conversation on top of the Empire State
Building, and she accepts his invitation to dinner. Dropping in at his apartment on the way, they decide to dine there as Patty announces herself an excellent cook. Don slips
out to buy food, and Patty is briefly visited by his ex-fiancée, Cynthia Slater (Dawn Addams), and not too briefly, by Cynthia's father David (David Niven), a middle-aged, practiced
charmer who, on her invitation, stays to dinner. A slight accident at the table occasions Patty to change her dress for Don's bathrobe.
