The film had a long development history. Peter Falk was cast as Al Percolo in 1983. In 1989, Rodney Dangerfield was attached to play Al with Sam Kinison attached to play Steve Nebraska.
When Steve Nebraska is pitching in front of Baseball Scouts at Yankee Satdium, during filming Keith Hernandez walked out of the dugout wearing Tennis Shoes, and Yankee owner George Steinbrenner told Henandez to put on spiked Shoes so he doesn't mess up the grass.
Steve holds a pile of plates with one hand as he hurls them Frisbee-style out of Al's kitchen window with the other hand. In the next shot, he's holding just one plate.
