After the original game's initial run, Williams released another 600 games in a "Limited Edition". The only differences were a sticker on the apron and various changes to the wiring and mechanics.
Sword of Rage has three editions, as is common for Stern: the base Pro edition, the Premium edition (featuring a transluscent upper playfield and different backglass art), and the Limited edition (a limited run featuring a mirrored backglass and a shaker motor).
What Could Have Been: In a DOS version of Eight Ball Deluxe (likely a separate build), a picture of the Black Knight was shown in the room, in place of Royal Flush, and Rudy is nowhere to be seen. Regardless of which game Amtex was planning, those plans fell through when they went bankrupt, and both games eventually made it onto The Pinball Arcade, with Black Knight first appearing on the Williams Collection prior to that.
What Could Have Been: Black Knight 2000 was originally planned to be a sequel to 1979's Flash. Programmer Ed Boon released photos of the original whitewood on his Twitter account, which showed that "B-L-A-C-K" was "F-L-A-S-H".

Sequel Gap: 2000 was released a full 30 years before this game.
Fake American: The English actress Marsha Thomason portrays Nicole at the end of the film with an over-the-top American accent, probably to distinguish the role from the British chambermaid Victoria (also portrayed by Thomason).
Similarly Named Works: The movie and the pinball game are completely unrelated. Black Knight the game is about defeating an evil warrior who calls himself "the Black Knight," and Black Knight the movie is a comedy about an African-American man who becomes a knight.
Throw It In!: The scene where Princess Regina trips over her bed sheets was not scripted, Jeannette Weegar really did trip and fall, but the director liked it so it was kept and put in the final cut.
