Midnight Lace is a 1960 American psychological thriller film directed by David Miller and starring Doris Day, Rex Harrison, John Gavin, Myrna Loy, and Roddy McDowall. The plot centers on a woman threatened by an anonymous stalker who has a hard time convincing others of what is happening. The screenplay by Ivan Goff and Ben Roberts was based on the play Matilda Shouted Fire by Janet Green. The new title referred to a lacy dress that Day's character purchases early in the film and wears at the climax.
The film was released theatrically in the fall of 1960. Day was nominated for the Golden Globe Award for Best Actress, and costume designer Irene Lentz earned an Academy Award nomination for Best Color Costume Design.
