Writer/director Billy Morrissette got the idea for setting Macbeth at a restaurant while in high school. He was working at a Dairy Queen in South Windsor, Connecticut, and was "reading a lot of Shakespeare at the time".
Among the 1970s trends, fads and inventions depicted in the film are: drive-thru restaurants, vegetarianism, Yahtzee, chicken bites with dipping sauces, tanning salons, the Magic 8 Ball, "MAD" Magazine (with the folding back-page pictures), fondue and streaking.
The menu at McBeth's seen briefly during a montage includes the following options: McBeth, McBeth with Cheese, Big McBeth, McBeth McBeth, Fishy McB, Little Chicken McBeth (5 piece), Big Chicken McBeth (8 piece), and fries.
According to director Billy Morrissette (on the DVD commentary), Pat McBeth's line "Fuck! Fuck! Fuckity-fuck!" was written into the script because star (and Morrissette's wife at the time), Maura Tierney yelled that once when he startled her.
