* ActorAllusion While re-enacting one of the murders, Smecker raises his hands up to the heavens, a reference to Creator/WillemDafoe's death in the movie ''Film/{{Platoon}}''.
* BillingDisplacement:
** Creator/WillemDafoe is ''not'' the main character of the first film, despite what the poster in the main page may tell you.
** Peter Fonda doesn't appear until the last 20 minutes of ''All Saint's Day'', yet still got billed over Creator/BillyConnolly (Il Duce [[spoiler:and the father of Connor and Murphy]]).
* BoxOfficeBomb: Both films:
** First film: Budget - $6 million. Box Office - $30,471.
** Second film: Budget - $8million. Box Office - $10.6 million.
* CaliforniaDoubling: Both films are set in Boston, but, apart from the flyover establishing shots, were filmed in Toronto. The CN Tower and Toronto Dominion bank locations can be seen in various shots.
** In a more specific example, the church scene at the start of the first film was shot in an Anglican Church rather than a Catholic Church, due to the producers being unable to convince any Catholic diocese to allow them to film on their property. The Anglican traditions are considered [[ChristianityIsCatholic about as close to Catholicism as non-Catholic Christian churches get]], but you can still spot a few differences in the service as shown.
* CompletelyDifferentTitle:
** In Spanish, the movie is known as ''Los santos del infierno'', or "The Saints of Hell".
** In German, it's "Der Blutige Pfad Gottes", meaning "The Bloody Path of God".
** In Japanese, it's ''Jyokeinin'', or "Executioners".
* TheDanza: Carmine [=DiStephano=] plays Augustus [=DiStephano=], a retired mob boss. Also, David Della Rocco is played by none other than a man named David Della Rocco.
* DawsonCasting: A rather bizarre example in that, in the sequel, Creator/JuddNelson plays the son of the BigBad of the first film, played by Carlo Rota, when Nelson is actually a year and a half older than Rota (Nelson was born on 1959 and Rota was born on 1961).
* DevelopmentHell: The second film took ''ten years'' to make due to a lack of funding and Troy Duffy's ego. The third film, thus far, seems to be in the same position. Duffy has said if negotiations go through, the story may be continued in a TV series, but the progress seems to be going slowly.
* EnforcedMethodActing: Apparently Creator/BillyConnolly was so stoked to be PlayingAgainstType so radically in the role of Il Duce and having so much fun playing a psycho with guns strapped all over him that they had to add the huge cigar the character constantly smokes because unless they stuck something in his mouth he simply couldn't stop smiling.
* FakeRussian: Fat Man (Yuri Petrova) is the only Russian played by an actual Russian.
* InvisibleAdvertising: The film was all ready to be released, but unfortunate timing meant it had to be released quietly. The second movie was set up this way at first, but positive reception among the fans gave it two wider releases.
* PlayingAgainstType: Il Duce, the [[TheStoic stone-cold]] veteran [[HitmanWithAHeart hitman]], is played by ''Creator/BillyConnolly'' of all people. He's done serious roles before, but not like ''this.''
* WhatCouldHaveBeen:
** Creator/MarkWahlberg turned down one of the lead roles in order to star in ''Film/BoogieNights''.
** Troy Duffy expressed interest in casting Stephen Dorff, Creator/BrendanFraser, Nicky Katt, and Creator/EwanMcGregor, with two of them as the brothers, but no decisions were finalized. Duffy flew to New York to meet with [=McGregor=] and offer him one of the lead roles. At a night out, Duffy got drunk and they got into an argument over the death penalty and [=McGregor=] passed on the film. This led to Miramax putting the film in turnaround.
** Creator/KennethBranagh, Creator/RobertDeNiro, Creator/KevinSpacey and Creator/PatrickSwayze passed on the role of Paul Smecker. Also considered were Creator/BillMurray Creator/MikeMyers and Creator/SylvesterStallone.
** Troy Duffy dismissed several casting choices for the film - he refused to meet with Creator/BradPitt because he'd already played an Irishman in ''Film/TheDevilsOwn'' and rejected Creator/KeanuReeves and Creator/EthanHawke, calling the former "a fucking punk" and the latter "a talentless fool".
