Julie Christie was supposed to be the lead
from trivia:
>>Jennie Linden was 11th hour casting choice replacing a actress who dropped out to do another film.<<
according to Jimmy Sangster's commentary on Fear in the Night, Julie Christie was cast as the lead and pleaded with the filmmakers to let her go so she could film Darling, which eventually got her an Oscar.
