20 Things You Somehow Missed In Friday The 13th (1980)
3. Acting Against Nothing
In Friday the 13th, the audience starts off by following camp cook, Annie as she hitchhikes to Camp Crystal Lake. This can lead to the mistake belief that she will be the film's final girl.
As they follow Annie's journey, they see her accept a lift part of the way to the camp from truck driver, Enos, who attempts to warn her not to go to the infamous "Camp Blood".
However, neither Robbi Morgan nor Rex Everhart were actually acting alongside each other during this scene. For her scenes in the truck, Morgan either spoke her lines to an imaginary Enos or performed opposite Tom Savini's assistant, Taso N. Stavrakis.
