According to David Spade, he and Chris Farley got into a physical altercation on the set. Spade had gone out for a drink with Rob Lowe the night before. Farley had become very jealous and angrily repeated "How's Rob Lowe?". He stepped on Spade's hand and the fight began. After the fight, Spade walked off the set and refused to continue filming.
Rob Lowe played the supporting role of Tommy's stepbrother and is uncredited. The reason for this is because Rob was contractually obligated to Stephen King's The Stand (1994) at the time, so he took the part simply as a favor for friend Chris Farley.
David Spade's character Richard Hayden says that 'Big' Tom, played by Brian Dennehy was like a father to him. Brian Dennehy would go on to play David Spade's father as Red Finch in the TV comedy Just Shoot Me! (1997)
