In early 1949, her parents arrived in London to make
Stage Fright, Hitchcock's first British-made feature film since emigrating to
Hollywood. Pat did not know she would have a walk-on part in the film until her parents arrived. Because she bore a resemblance to the star,
Jane Wyman, her father asked if she would mind also doubling for Wyman in the scenes that required "danger driving". She had supporting roles in three of her father's films. (Hitchcock has a small joke with her first appearance on his show – after saying good night and exiting the screen, he sticks his head back into the picture and remarks: "I thought the little leading lady was rather good, didn't you?") She also served as executive producer of the documentary ''
The Man on Lincoln's Nose'' (2000), which is about
Robert F. Boyle and his contribution to films. She edited one volume of
Random House's series of short-fiction anthologies attributed to her father,
Alfred Hitchcock Presents: My Favorites in Suspense (1959) and is acknowledged, under her married name, much in the way
Robert Arthur Jr. or
Harold Q. Masur were acknowledged as the "open secret" editors in other Random House volumes in the series (and in the subsequent
Dell Books paperback reprints). For several years, she was the family representative on the staff of ''
Alfred Hitchcock's Mystery Magazine. 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. A biography of her mother, Alma Hitchcock: The Woman Behind the Man'', was co-written with
Laurent Bouzereau, and published in 2003. ==Personal life==
