Sara Karloff Cotten
Did You Know?
[about her father Boris Karloff
] A lot of people don't know that Frankenstein
(1931) was his eighty-first film. Of course nobody ever saw the first eighty.
Since her father never changed his real last name of Pratt to "Karloff", and since she has been married twice, and she wasn't raised by her father but by her single mother since the age of 8, and she is not an actress, it is unclear why Sara calls herself "Karloff".
