Trivia / Professor Layton vs. Phoenix Wright: Ace Attorney

• The Other Darrin: Due to the game being dubbed in Britain, some of the characters' voice actors are different from the U.S. dubs.
  • Phoenix Wright is voiced by Trevor White instead of Sam Riegel, his voice actor from Ultimate Marvel vs. Capcom 3. This was only temporary, as Riegel went on to be Phoenix's official voice actor in the games from that point forward.
  • For the Japanese version of the game, Takayuki Kondō and Satomi Hanamura do not reprise their roles as Phoenix and Maya. That honor goes to Hiroki Narimiya and Mirei Kiritani, their actors from the live-action film released in the same year.
• Role Reprise: While Phoenix and Maya's usual voice actors from the games don't play them here, Hiroki Narimiya and Mirei Kiritani reprise those roles after having played them in the movie.
• What Could Have Been:
  • The announcement trailer features a lot of elements that were either changed or removed from the story over the course of development, including:
    • Luke in his prequel trilogy outfit because the team was still deciding if they should include Emmy. Ultimately, they decided not to and shifted the game's timeline forward a bit.
    • Phoenix and Layton openly disliking each other from the start, with the Professor acting as a prosecutor for Espella early in the story.
    • A group of hooded townspeople chasing Espella through the night, Torches and Pitchforks in hand.
    • Different designs for most other characters, including a much more youthful Storyteller.
    • The whole "how could you have known what's in a book you never read" element. The concept of the book containing the entire past, present, and future history of Labyrinthia exists, but isn't used in that way.
    • The trailer's tagline is "This time the puzzles are full of contradictions" but this only comes up once in the final game, though it's at a critical point.
  • The art book contains concept sketches for "dark" counterparts of both Professor Layton◊ and Phoenix Wright◊, Labyrinthian attire for Edgeworth and Larry◊, and a robotic Layton◊. There were also very early plans to have Professor Layton characters drawn in Ace Attorney's art style, and vice versa◊.
    • The same art book contains concept art for an unused villain wearing a skull mask and tuxedo, who also carried masks of the main characters' faces.◊
  • Espella's original design featured an armored gauntlet she'd use to hide some kind of brand she received for being accused of witchcraft, but the designers thought that made her look too much like a warrior, so it was removed.
  • Eve the cat was originally going to exist as an illusion that only Espella could see, but the designers felt that it made the story really sad due to the events in the game, so it was changed.
  • The famous Phoenix on a horse◊ art is never seen in game. It is given a small nod, though: when you examine the horses out in the forest, Maya wants to know what it will take to get Phoenix on one, no matter what!
  • Carmine Accidenti was originally going to be drawn in the cartoony Layton style, but his designer was told to use the Ace Attorney style instead.
