Sean Archer's prison was filmed at Eagle Rock Substation. The costume department of the crew made 180 pairs of boots that can be fixed by magnetic force, each pair 13 pounds. The producer had hoped that John Woo could remove the slash in the title, but John Woo insisted on keeping it because he was afraid that the audience would misunderstand that the film was a hockey movie (Face Off is a hockey term, meaning kick-off). The speedboat chase at the end of the film was originally designed for the ultimate goal. Nicolas Cage once said that he was driving a beige Volvo in Brave Island. In the film, after Nicolas Cage escaped from prison, he stole a beige Volvo. The prison at sea in the film is called "Erewhon", which is the antonym of "nowhere". The magnetic boots in prison belong to the super horsepower brothers. The name of Castor Troy in the film comes from Greek mythology. The choir in the film is a non-profit choir in Los Angeles. There are many iconic scenes of John Woo in the film, such as Castor Troy's use of double guns, Castor Troy's reflection in Dr. Walsh's glasses, Sean and Castor's back-to-back conversation across obstacles, pigeons and church gunfights, etc. Arnold Schwarzenegger and Sylvester Stallone were the first candidates to star in this film, and later john Travolta and Nicolas Cage were more suitable as directors. According to producer Barry Osborne, many thrilling scenes in the film, such as the fight on the ship and the plane running off the runway, were originally intended to be filmed on the green screen, but in order to serve the authenticity of the story, they decided to shoot these scenes. At first, Nicolas Cage refused to play Castor Troy because he was not interested in playing the bad guys. Later, he learned that he was playing a hero for most of the film, and he quickly signed the role.
