Cunningham wanted to make the Mrs. Voorhees character "terrifying", and to that end he believed it was important that Palmer not act "over the top." There was also the fear that Palmer's past credits, as more of a wholesome character, would make it difficult to believe she could be scary. Palmer was paid $1000 per day for her ten days on set. Ari Lehman, who had previously auditioned for Cunningham's "Manny's Orphans", failing to get the part, was determined to land the role of Jason Voorhees. According to Lehman, he went in very intense and afterward Cunningham told him he was perfect for the part. In addition to the main cast, Walt Gorney came on as "Crazy Ralph", the town's soothsayer. The character of Crazy Ralph was meant to establish two functions: foreshadow the events to come, and insinuate that he could actually be the murderer. Cunningham has stated that he was apprehensive about including the character, and is not sure if he accomplished his goal of creating a new suspect.
