Pat Hitchcock is ninety today, and she hasn’t done a motion picture in forty years. (That last film — 1978’s Skateboard — was the only role she ever took that didn’t involve her father, Sir Alfred Hitchcock, who’d made his last film, Family Plot, two years before.) She’d spent the 1940s studying acting for the stage, and in 1950 appeared in Sir Alfred’s Stage Fright, playing a jovial acting student named Chubby Bannister. (She was never all that chubby, really.)
Two of her credits were for smallish parts in great films: Strangers on a Train (1951) and Psycho (1960).
Note the medicine bottle in the second shot: this is Caroline, who has generously offered to share her tranqs with her coworker, played by Janet Leigh.
Pat also did several episodes of Alfred Hitchcock Presents, starting in 1955 with “Into Thin Air.”
In 1997, she talked to the BBC about Strangers on a Train:
As for our title, it’s a reference to 7 July 1928, the date of Patricia Alma Hitchcock’s birth — and the date the first loaf of sliced bread was sold, in beautiful downtown Chillicothe, Missouri, sliced with a machine invented by Otto Frederick Rohwedder (1880-1960).
