Bob Clark directed this film at the same time he was helming A Christmas Story (1983). A similar leg to the "major award" (the racy mannequin's leg in fishnet stockings-lamp) makes an appearance when the kids are performing the sword-fight scene of William Shakespeare's "MacBeth" onstage. Christmas Story's leg lamp had a black shoe, whereas the leg in this movie had a red shoe.
The yellow 1947 Crosley convertible featured in this film was borrowed from a family member of the original Crosley Motors.
According to the '80s Rewind' website, the studio did not want to make A Christmas Story (1983) but allowed it, so 'Bob Clark' would make this sequel Porky's II: The Next Day (1983).
Like the first film, it was initially banned and re-rated 16 on appeal in Ireland. This is unusual considering a higher 18 rating was available at the time.
Bob Clark stated in the 2006 DVD commentary for Porky's (1981) 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.
