Willem Dafoe 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 Billy Connolly (Il Duce and the father of Connor and Murphy).
The Danza: 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.
Dawson Casting: A rather bizarre example in that, in the sequel, Judd Nelson plays the son of the Big Bad 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).
Development Hell: 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.
Enforced Method Acting: Apparently Billy Connolly was so stoked to be Playing Against Type 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.
Fake Russian: Fat Man (Yuri Petrova) is the only Russian played by an actual Russian.
Invisible Advertising: 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.
If you've seen both this movie and The Walking Dead, it may be weird hearing Murphy speaking with a Southern accent/Daryl speaking with an Oirish accent. Or it may be weird seeing Scud shooting up bad guys, considering his insistence that "I'm a lover, not a fighter."
