Halle Berry became one of only six actors in history (only five at the time) to possess both an Oscar and a Razzie, after her "win" for her infamous performance in this movie. She also became the first to accept their Razzie in person - walking out on stage proudly holding both Oscar and Razzie aloft. She gave a short acceptance speech: "I'd like to thank Warner Brothers, for making me do this godawful, piece of s**t movie!"
A rough cut of the trailer was put online a few months before the film's release, and drew such heavy criticism that it was quickly pulled. It was soon replaced with a new trailer which didn't feature any dialogue.
A Bengal cat, a domestic breed, was used in the film. Halle Berry loved it so much that she announced that she was going to adopt it. Some media sources inaccurately described the 13 pound housecat as a tiger which caused the Fund for Animals to send Berry a nasty letter.
The setting of the film is ambiguous, as the city is never called Gotham City nor are there any references to Batman or other DC characters. It is possible that it takes place in the original Batman film universe as a picture of Michelle Pfeiffer as Catwoman from Batman Returns (1992) can be seen in the pile of old catwomen pictures that Ophelia shows to Patience Phillips.
When production stalled in mid-2003, rumors circulated that Warner Bros. would scrap the project and instead incorporate the character of Catwoman into Batman Begins (2005), but with Halle Berry still in the role.
The film was originally planned to be released in IMAX format (using IMAX DMR technology) but was cancelled because Warner Bros. decided that visual effects delays did not give IMAX enough time to re-master the film for release on 23 July 2004. The promotional title "Catwoman: The IMAX Experience" was to be used along with the tagline "CATch Her in IMAX" on posters. The decision to cancel the IMAX release was announced 30 June 2004.
This movie features both Sharon Stone and Benjamin Bratt, Bratt was considered by producers for the male lead role in Basic Instinct 2 (2006), but Sharon Stone allegedly vetoed his casting because she did not consider him to be a good enough actor.
Frances Conroy was listed as a potential nominee on the 2005 Razzie Award nominating ballot. She was listed as a suggestion in the Worst Supporting Actress category for her performance in this film, she failed to receive a nomination however.
A remix of the Young Gunz song "Grown Man" featuring Kanye West was initially lined up to be the first single from the soundtrack. Due to label difficulties, the song was nixed for the R. Kelly and Britney Spears collaboration "Outrageous".
To help offset the film's poor box office showing, Village Roadshow Ltd. agreed to sell its 50% stake in Eye Shop (a mall advertising business) to its joint venture partner Ten Network Holdings Ltd. for $A14.9 million (US $10.6 million), which would give Village Roadshow a pre-tax profit of $A7.7 million (US $5.5 million). As a result, it expects a net profit after tax of $A45 million (US $32.2 million) for the year to 30 June 2005.
DVD contains some deleted scenes: dialog scene between Patience and Laurel after George disapproves of her work; chase scene with three dogs on a scrapyard after the resurrection; slightly extended love scene; omitted dialog between Catwoman and Laurel in her house (alternate); more Hollywood-like ending: Patience is painting a wall somewhere outside. Tom comes to her and tells that Wesley has confessed and the murders are officially closed. After some talking they kiss and the camera pans away...
