Joseph Zito had previously directed The Prowler (1981), but they wanted him to both direct AND write Friday the 13th Part 4. He said, "But I'm not a writer," to which they said, "Here's a contract paying you double to write and direct," and then he responded, "Yeah, I'm totally a writer." Zito used the extra salary to hire Barney Cohen to somewhat secretly write the script. Their process entailed Zito taking nightly one-hour phone calls with Phil Scuderi to discuss the story and script for Final Chapter. The next day Zito would meet Cohen in an apartment in New York to relay what notes and ideas Scuderi had offered, which they would then turn into new script pages to be sent later that day to Scuderi in Boston to be discussed again over the phone that night.
