According to James Woods, his role in this film was one of his toughest because his character had to constantly be angry with Michael J. Fox's character, who he found very likeable in real life.
One of James Woods' perks was to have his own personal hairdresser, at a cost to the studio of $6,000 a week. The average on-set hairdresser usually costs about a third of that.
In the movie theater where the Nick Lang movie is playing, and where the Party Crasher gets in the shoot-out with Michael J. Fox, there is a poster in the background for Dos pájaros a tiro (1990), which was also directed by John Badham.
This was the last movie to feature the 75th Anniversary variant of the 1990 Universal Studios logo. Every other feature from Universal after this movie, up until La armada de McHale (1997), used a short variant.
