Box Office Bomb: Budget, $65 million. Box office, $17,218,080. Numerous reports on the film's Troubled Production place the blame on Bruce Willis letting his ego run rampant, causing multiple re-shoots and editing wars. This ended up being Tristar Pictures final film before they were merged with Columbia.
Creator Backlash: Richard E. Grant really, really disliked working on the film. He even dedicated a chapter about the nightmare that was making the movie in his book With Nails.
Richard E. Grant regretted having worked on this film, given its Troubled Production. When Mark Kermode met Grant, he told him that he was one of the few people who liked the film. Grant's response? "It was a stinking pile of steaming hot donkey droppings and you are an idiot".
The Other Marty: Isabella Rossellini was originally cast as Anna Baragli. When the movie was delayed because of scheduling issues, the part was re-cast with Maruschka Detmers. She had to leave after a few days of shooting due to back problems. Andie MacDowell replaced her.
Troubled Production: The film gathered bad reaction before its release due to a disastrous production - egos running rampant, constant rewrites, clashes between director and star, you name it.
In the earlier versions of the script most of the third act took place at the Kremlin, where a scale model of Da Vinci's helicopter was being kept.
Minerva Mayflower was not in the original drafts. This came about because there was initially supposed to be a single antagonist originally meant for a male actor, but Michael Lehmann suggested casting Audrey Hepburn in the film, and the villain was subsequently rewritten as a villainess so that Hepburn could play that part. Negotiations between the producers and Hepburn broke down, but Bruce Willis suggested to take both villains from the earlier drafts and make them a couple.
Madonna was offered the role of Anna Baragli, but she was busy touring. Willis asked that Famke Janssen be considered for a role after seeing her in a Pantene television commercial. She screen tested for a role but was not cast. The two later acted opposite each other in Once Upon A Time In Venice.
There was a whole subplot about "Little Eddie," Hawk's pet monkey that Tommy was taking care of, who was kidnapped and executed just before Hawk was released from prison. Hawk ends up accusing Cesar Mario of doing it (Cesar denies it), and Kaplan tells Hawk he killed "Little Eddie" just before leaving Hawk and Tommy to die in Anna's apartment. When Hawk dispatches Kaplan, he pins a photo of Little Eddie in a graduation cap to him and tells him "This is for Little Eddie" before pushing him off the ledge onto Mayflower's runaway limo.
Written by Cast Member: Bruce Willis shares story credit with record producer/songwriter and future head of music at Fox, Robert Kraft (Willis had been friends with Kraft in his pre-stardom bartender days, Kraft had written a song about the "Hudson hawk" with what would be the basic story of the movie).
