[3] As a child, Hitchcock knew she wanted to be an actress, and made her first onscreen appearance as an uncredited extra alongside her mother in Sabotage (1936).
[2] In early 1949, her parents arrived in London to make Stage Fright, Hitchcock's first British-made feature film since emigrating to Hollywood.
[1] In Stage Fright (1950), she played a jolly acting student named Chubby Bannister, one of Wyman's school chums; Strangers on a Train (1951), playing Barbara Morton, sister of Anne Morton (Ruth Roman), the lover of Guy Haines (Farley Granger); and Caroline in Psycho (1960).
In this role, she offers to share her tranquilizers with Marion Crane (Janet Leigh), having received them from her mother prior to her wedding night.
She supplied family photos and wrote the foreword of the book Footsteps in the Fog: Alfred Hitchcock's San Francisco (2002) by Jeff Kraft and Aaron Leventhal.
[2] Hitchcock died of natural causes in her sleep at her home in Thousand Oaks, California, on 9 August 2021, one month after her 93rd birthday.
