Writer/Director Bob Clark gathered material for the movie over a 15 year period. The story is composite of incidents collected from the males of his generation along with some of his own personal memories from growing up in high school.
Bob Clark stated in the 2006 DVD commentary that he used his real life High School and College experience as the basis for various characters, and compares himself closest to Pee Wee, Billy and Tommy (the brains); others characters were based in real life friends or people he went to school and college with.
The meaning and relevance of this film's "Porky's" title was explained by 'Halliwells' who explicated that the "title refers to a redneck establishment out in the everglades known for its available women".
Chuck Mitchell wasn't the only one considered for the role of "Porky". Broward county sheriff's Deputy Don Lydanne, who was also the personal Bodyguard of the Sheriff of Broward County Ken Jenne, stood at 6'8 and 320 lbs. However, he was turned down for the role due to his "slimmer" physique and lack of a huge stomach.
This American looking movie was actually produced by a Canadian outfit, Astral Bellevue Pathe Inc. and was essentially a Canadian production despite the picture being financed by USA company Melvin Simon Productions and entirely shot in Florida.
The character name of Beulah Balbricker (Nancy Parsons) was a joke reference to her being a "ball-breaker". She is even referred to being a "ball-breaker" in one scene. The character in the closing credits is simply billed as Balbricker.
