Sorry, Wrong Number is a 1948 American thriller and film noir directed by Anatole Litvak, from a screenplay by Lucille Fletcher, based on her 1943 radio play of the same name.
The film stars Barbara Stanwyck and Burt Lancaster. It follows a bedridden woman who overhears the plot of murder while on the telephone. She attempts to help her husband solve the mystery and prevent the crime. Stanwyck was nominated for the Academy Award for Best Actress.
It is one of the few pre-1950 Paramount Pictures films which remained in the studio's library (the rest are currently owned by NBCUniversal).
