Fan Community Nicknames: Numerous types continue to float around, such as Humanites and Humaniacs which were coined during the series promotion in May 2013. After the series first pilot airing it deviated into FanBots and Badge Rabbits/Bunnies. The names are still up in the air.
Humanite is viewed as the proper or fancy term.
FanBot is the colloquial and slang term.
Out of Order: FOX's practice of airing fledgling shows out of order continues. The "second" episode, "Skin", is actually episode 5, according to IMDb. So far the effects are John going from being pretty hard nosed and unfunny to him actually being more relaxed with Dorian and socially awkward. The possibility of skipping the early episodes would likely have explained this as well as John's therapy sessions about the bad raid.
After airing episodes five through eight in production order after the pilot, episodes two and three by production order aired as numbers eight and six, respectively, bookending episode ten. Episode nine was then aired as episode nine, followed by episode four, with eleven through thirteen airing in order.
Screwed by the Network: Fox did this by dumping originals against The Olympics. After having previously pulled the show for two weeks to do two-hour episodes of Sleepy Hollow and The Following. Not to mention that it didn't get picked up past the original thirteen episode order. And all this despite the fact that the ratings were actually decent by Fox standards. Oh, and they aired it completely Out of Order. Yup, it's Fox all right.
Throw It In: Karl Urban has said that quite a few of the scenes between Kennex and Dorian in the car were a result of him and Michael Ealy just bouncing improvised dialogue off of one another. The showrunners were apparently cool with it so long as they shot a take with the scripted dialogue first. According to Urban, the "you're scanning my balls?" scene and the scene where Dorian exposes himself were both a result of this note (he was also quick to point out that Ealy did not actually pull out his penis on set).
Completely Different Title: The original title is Milano odia: la polizia non può sparare, which roughly translates to "Milan Hates: The Police Can't Shoot". The English-language title was courtesy of a misguided American distributor who inexplicably tried to market the film as a horror movie.
Troubled Production: Umberto Lenzi and Tomas Milian had what the former called a "love-hate" relationship. Lenzi was an impulsive, hotheaded director, and Milian was a Method actor who often ad-libbed lines and consumed intoxicants before shooting scenes to get in his character's headspace. The two eventually struck a balance, and would wind-up making 6 more films together.
Marc Porel was originally offered the role of Giulio. Lenzi had a meeting with him and found him to be "unreliable from both a human and professional point of view." Lenzi told the producer "It's him or me."
Richard Conte was originally cast as Grandi, but died shortly before filming began and production could not be halted. The first available actor for the part was Henry Silva. Silva at the time was mostly known for playing villains and killers so director Umberto Lenzi had to work hard to try to make him fit the character of a cop.
