The part of Bill was given to Harry Crosby, son of Bing Crosby. Robbi Morgan, who plays Annie, was not auditioning for the film when she was offered the role; while in her office, Hughes looked at Morgan and proclaimed "you're a camp counselor." The next day Morgan was on the set. Morgan only appeared on-set for a day to shoot all her scenes. Rex Everhart, who portrays Enos, did not film the truck scenes with Morgan, so she had to either act with an imaginary Enos, or exchange dialogue with Taso Stavrakis—Savini's assistant—who would sit in the truck with her. It was Peter Brouwer's girlfriend that helped him land a role on "Friday the 13th". After recently being written off the show "Love of Life", Brouwer moved back to Connecticut to look for work. Learning that his girlfriend was working as an assistant director for "Friday the 13th", Brouwer asked about any openings. Initially told casting was looking for big stars to fill the role of Steve Christy, it was not until Sean Cunningham dropped by to deliver a message to Brouwer's girlfriend, and saw him working in a garden, that Brouwer was hired.
