Trivia / Kamen Rider Zi-O: Over Quartzer

• Descended Creator: Barlckxs is played by ISSA, who, along with Shuta Sueyoshi of AAA, sang the Zi-O opening song "Over Quartzer." Incidentally, the unnamed members of Quartzer are all played by the other members of his band, DA PUMP, who performed the theme song for the movie.
• Foiler Footage: To keep the extras on hand from spoiling Kamen Rider Zero-One's Early-Bird Cameo, the scene was originally filmed with Kikaider 01 in his place; this foiler scene even made it into some of the trailers.
• In Memoriam: This movie also dedicated to Yoshinori Watanabe, the vice president of Toei who passed away in 20 May 2019.
  We miss you, Mr. Yoshinori Watanabe (1930-2019).
