The film based on the video game series:
- Actor Allusion:
- Big Name Fan: Believe it or not, Marxist philosopher and cultural critic Slavoj Žižek voted for it for Sight & Sound 's poll regarding the best films of all time. Even the writer of the piece seems confused by this decision.
- Executive Meddling: The infamous "train duel" scene was filmed in a rush after the director was fired over conflicts with the studio.
- Money, Dear Boy: Timothy Olyphant has admitted in interviews that he did the film as a means to help pay for his house after Deadwood was cancelled.
- What Could Have Been: In the near-final script, Agent Markov is revealed as the main villain who wants to replace the President-to-be with an doppelganger loyal to him. 47 is pursued by Spetsnaz (not the other clones), and the whole plan is foiled by Mike (who recorded Markov's confession after slipping one of 47's spy microphones under his lapel). 47 manipulates Markov into shooting the President during Udre's funeral, and then blows him up anyway.
The comic book:
- I Am Not Shazam: Tommy is not referred to as "Hitman" in the series, nor does he identify by that as anything but the job he does, but his guest appearances in comics often have people identify him by that name.
- Screwed by the Network: DC became notoriously gun-shy about promoting Hitman after the Columbine High School shootings in 1999, which is one of the factors that ultimately led to its cancellation.
- Throw It In: One time the writers were coming up with the silliest ideas for comic characters and when Dog Welder was suggested the contest was over. Lol and behold, the character was made up.
The video game series:
- Executive Meddling: This is the reason why there was such a long gap between Blood Money and Absolution. Apparently the developers started work on a new game for release in 2009 or 2010, but Eidos decided that the Kane and Lynch franchise (also developed by IO Interactive) was going to be the next big thing (spoiler: it wasn't) and ordered them to produce a sequel to that game instead. Square Enix, on the other hand, were far less enamored with Kane and Lynch, and upon buying out Eidos they put that franchise out to pasture and let IO get back to its flagship series.
- Hey, It's That Voice!:
- In the original English version:
- Vivica A. Fox as Lasandra Dixon
- Traci Lords as Layla. Her other voice credits include Madam Cassandra in True Crime: New York City.
- In the Japanese version:
- In the original English version:
- Mean Character, Nice Actor:
- 47 and Diana on their off-hours.
- Actually, there was a bit during the press conference for Absolution where Bateson was asked what traits he shares with 47, and he jokingly threatened to kill the reporters. "I'm very happy, very well-adjusted."
- Meaningful Release Date: Absolution was released in territories other than Japan on the 20th of November in 2012, during the 47th week of that year.
- Name's the Same: Agent Smith and Agent Smith. Lampshaded in Contracts.
- No Export for You: An odd version. Contracts was unavailable on Steam despite all of the other Hitman games being released on the platform due to a music licensing issue. It has since been added in the Steam store in January 2014.
- Production Foreshadowing: of Deus Ex: Human Revolution. The Anatomy Lesson of Dr. Nicolaes Tulp makes a brief appearance in the opening of Blood Money's "Curtains Down".
- The Other Darrin: For Absolution, the original voice actress for Diana (Vivienne McKee) was replaced by Marsha Thomason (best known for her roles on Lost and White Collar).
- Agent 47 himself nearly got this treatment in Absolution too, when his voice actor, David Bateson, was revealed to have been snubbed by IO. Following many fans protesting/begging/protesting and begging at the same time, Bateson was called back and did the voice work (but not the motion capture) again in Absolution.
- Throw It In: According to Word of God, Absolution's Instinct mechanic began life as a developer tool to determine pathfinding after the AI became so insanely complex they could no longer playtest properly. It was later added to the game proper, provoking much outcry, but it doesn't do much in higher difficulties other than helping you blend in.
- What Could Have Been: Iron Galaxy Studios bet on the right to make Hitman GO and lost, according to CEO Dave Lang although he also states that the end result is probably way better than whatever they would have come up with.
