• Notorious (1946) - Sebastian and his mother
• Vertigo (1958) - Midge says to Scottie "You're not lost, mother is here."
• North by Northwest (1959) - Roger and his mother ("When I was a little boy, I wouldn't even let my mother undress me.")
• Psycho (1960) - Mother ...isn't quite herself!
• The Birds (1963) - the relationship between Mitch and Lydia
• Marnie (1964) - the relationship between Marnie and her mother
