The scenes with Calvin were filmed twice: once with dwarf actors Linden Porco and Gabriel Pimentel together with the other actors, and once with Marlon Wayans alone wearing a green bodysuit against a green screen. In post-production, Porco's and Pimental's heads were replaced with Marlon's. Their bodies were also painted brown in order to match Marlon's face.
The basic plot of this movie is taken directly from the Bugs Bunny short Baby Buggy Bunny (1954). Bank robber Baby Face Finster, who is very short, masquerades as an orphan baby to recover his loot from Bugs after it falls down his rabbit hole.
Kelly Coffield Park also starred with Shawn Wayans and Marlon Wayans in Scary Movie (2000) and the episode Marlon Joins a Cult (1998) on The Wayans Bros. (1995) TV show, and most famously with other Wayans on In Living Color (1990).
(at around 21 mins) When in the doctor's office, Calvin's tattoo on his arm reads "82nd Airbourne". Airborne is misspelled to the British rendering of Airborne ("Airbourne"). The 82nd Airborne Division is a paratrooper infantry division of the U.S. Army. This also alludes that Calvin was in the service, though it is never mentioned.
