Rodney Dangerfield has stated that the part of Monty Capiletti was the closest to his real-life persona.
During the scene where Rodney Dangerfield is watching television and flipping channels, you can hear "All we need is one pin, Rodney!" which is from a Miller Lite beer commercial starring Dangerfield.
Bill Murray was originally cast in the role of Paddy, but dropped out with the part in the end being cast with Tom Noonan.
Throughout the movie Monty is seen only drinking Miller Beer, this is because Rodney Dangerfield was the spokesperson at the time of filming.
This put a stop to Die schrillen Vier auf Achse (1983) three-week run at the top of the US box office.
