 Kim Novak played Kit Marlowe, which was the pseudonym that Harry  Cohn, CEO of Columbia Studios, suggested she should change her name  to when she was a young starlet. Novak supplied the writers other  inside jokes when they were naming Kits aliases: Kits real name is  Susan Cameron, the name of Novaks agent during her time on the set.  Another alias, Madeleine McKittrick, was a combination of the first  name of one of her characters in Vertigo and the McKittrick hotel on  Eddy Street in San Francisco where Vertigos Maddy lived.
