Lead actors Tom Selleck and Paulina Porizkova had such a bad time on this movie that by the time filming ended, they refused to be in the same room with each other. To make the ad poster for the film, director Bruce Beresford had to photo shoot them both separately, and digitally combine the two photos using Paintbox software, so that it looked like Selleck was standing behind Porizkova with his arms around her.
The name of the annual clown meeting which was in the memory of the greatest clown of all was "The Funeral of Grimaldi". Several scenes in this movie take place at this event towards the end of the film. Grimaldi refers to real-life clown Joseph Grimaldi (1778-1837), who is the most celebrated English clown in history, and just like in the movie, there really is a "Funeral of Grimaldi" held every year on the first Sunday in February, at the All Saints' Church in London. His actual birth and death dates were also reproduced on poster artwork seen in the film, these being Born: 18th December 1778 and Died: 31st May 1837.
The Eastern European nation that the character of Nina (Paulina Porizkova) came from was the south-eastern and central European country of Romania. In real life, Porizkova comes from the nearby central land-locked European nation of Czechoslovakia which is now known as the Czech Republic.
Names of fictional Peter Swift detective novels written by Phillip Blackwood (Tom Selleck) seen on dustcover artwork mainly at the start but at times also throughout the movie included: "Her Alibi", "The Dying Habit", "Sayonara, Cyanide", "Counsel for Crime", "Death Game Funeral", "Looks Like Curtains", "The Dying Position", "Murder With Honor", "Bullets Never Forget", "Computer Virus", "A Croak of Corpses", "Guns I've Loved", "Shakes Hands with a Bullet", "Murder by Modem", "One Down and Two Dying", "Death of a Critic", "Murder Becomes Her" and "Wake Me when I'm Dead".
There's a line in the movie where Tom Selleck's character makes a quip to Paulina Porizkova's character about killing a bug by swatting it with a rolled-up copy of Sports Illustrated magazine. In real life, Paulina Porizkova gained fame after appearing on the cover of this very magazine. She appeared on the cover of the Sports Illustrated Swimsuit Issue in 1984 and again in 1985.
Actress Paulina Porizkova played a character, "Nina", whose first name rhymed with her own. This film was the second consecutive movie where her character name rhymed with her own, as in her previous film Anna (1987), Porizkova had played a character called "Krystyna".
