Trivia: Castlevania: Symphony of the Night
- Beam Me Up, Scotty!: Whenever Dracula's famous question is quoted, the word "little" is commonly forgotten.
- Disowned Adaptation: Castlevania producer Koji Igarashi wasn't very fond of the Sega Saturn port, which was developed by a different team (Konami Computer Entertainment Nagoya), as noted in the June 2007 issue of Play Magazine:
"I understand why fans who've never played the Saturn version would be interested in those features, but I really, really don't feel good about them. I couldn't put my name on that stuff and present it to Castlevania fans." — Koji Igarashi
- Dueling Dubs: The PSP version vs. the original PS1 version, which can be now found in the Playstation Store.
- Hey, It's That Voice!: Several.
- Original (Japanese): Dracula is Cell, Alucard is Byakuya, Maria is Servbot
- Original (English): Dracula is Harry Mason, Richter is Chris Redfield, Alucard is the Tekken 5 narrator, and Shaft is the original Super Smash Bros. announcer.
- PSP Version: Alucard is Sasuke, Richter is Jin Kisaragi, Dracula is Ragna the Bloodedge, Maria is Shanoa, Shaft is Bang Shishigami, The Succubus is Faye Valentine / Haruhi / Konata, Death is Roy Mustang, and the Narrator and the Master Librarian are Aizen... and another Richter.
- Don't forget the end theme! Cynthia Harrell also sang the theme song of Metal Gear Solid 3: Snake Eater.
- Sequel First: Unless you count the SNES version of Castlevania: Rondo of Blood.
- Marth Debuted in Smash Bros. : Shaft was cut out from the SNES version of Castlevania: Rondo of Blood despite appearing in the original PC Engine game, so most players outside Japan first knew about him in this game.
- What Could Have Been: Unused voice acting featured in the sound files of the PS version reveals an unmade ending in which Maria becomes a demon, much like Annette did in Rondo.
