- Dyeing for Your Art:
- Follow the Leader: The skull logo; this version of The Punisher skull had been used in other Punisher-based merchandise past the release of the film like shirts, car decals, gun customization, and the skull used in the 2017 Punisher TV show is based heavily one the one in the 2004 film.
- Inspiration for the Work: For inspiration, director Jonathan Hensleigh and cinematographer Conrad W. Hall looked at dozens of action films from the 1960s and 1970s, such as the Dirty Harry series, The Getaway, The Good, the Bad and the Ugly, The Godfather and Bonnie and Clyde. In an interview, Hensleigh also stated the film pays homage to Mad Max and Othello.
- Saved from Development Hell: Marvel Studios began development for a new Punisher film as early as 1997.
- Stillborn Franchise: Plans for a sequel remained in Development Hell until Thomas Jane pulled out. What came next was the reboot Punisher: War Zone.
- Throw It In!: Much of the torture exchange between Will Patton and Ben Foster was improvised.
- What Could Have Been:
- Howard Saint was originally named Bruno Costa.
- Originally, The Punisher was supposed to have a sidekick, David Lieberman, alias Microchip, the Intel man. He was written out as director Jonathan Hensleigh had an intense dislike of the character.
- The first scene in the movie was originally intended to be a battle set in Kuwait during the first Gulf War, but the reduction in budget rendered that impossible.
- Hugh Jackman turned down the lead role in order to star in Van Helsing. This would have been the second time he played a Marvel anti-hero.
- Patrick Swayze was considered for Howard Saint.
- In the script, Livia Saint was supposed to commit suicide and not be killed by Howard Saint. She died the same way showed in the movie, but in the script she willingly threw herself off the bridge.
