Alec Cawthorne is a curious case in terms of film credits. His only film credit, in the classic Kanlı Şaka (1972) is a mere case of credit only despite being listed along heavyweights and Oscar winners Laurence Olivier and Michael Caine. Cawthorne does not exist - just as his other credit only colleagues John Matthews, Eve Channing and Teddy Martin (all in their only film "appearance"). The studio's idea was to create the feeling of having another actor and another character rather than just a filmed play with two major stars in order to attract audiences. The ploy worked and many viewers keep on wondering where exactly those credit only actors appeared and where are they now.
