Clark teamed up with Roger Swaybill on a film, "Breaking Point". When Clark fell ill with mononucleosis in 1979, he dictated the story of "Porky's" to Swaybill, who then wrote a draft of the script. Every studio in Hollywood turned down the project. Clark eventually obtained finance from Melvin Simon Productions and a Canadian firm, Astro Bellevue Pathe. The film had to be made in Canada to obtain government tax benefits. This meant Clark, who was an American, got sole screen credit as writer. However, Swaybill was reimbursed with a six-figure sum and was co-writer on the sequel.
