Trivia / Get a Horse!

• Executive Meddling: According to the short's director, the black and white introduction was going to be a little longer, but execs insisted that Mickey fall into the color, 3D world as soon as possible, fearing that the black and white opening would lose audiences' interest very quickly. Also, the idea of creating a short involving classic Mickey had been thrown around the studio for many years, but were constantly shot down by execs who felt nobody today would accept Mickey in his original look.
• Hey, It's That Sound!: A phone left on the stage plays the Marimba ringtone.
• No Export for You: For some reason, the short is absent from the 3D Frozen (2013) Blu-ray discs issued in some countries (notably, the Southeast Asian release). The option is there in the menu, but selecting it causes the player to go berserk and drop you in a random point in the feature movie instead, indicating that the short was hastily removed from the disc but the menu structure was not updated.
• The Other Darrin: Pete's non-recycled dialogue for the short is provided by Will Ryan instead of Jim Cummings.
• Posthumous Credit: The voices of Walt Disney (d. 1966), Marcelite Garner (d. 1993) and Billy Bletcher (d. 1979) are reused via archival audio from the previous Mickey Mouse shorts.
• Role Reprise: Via archive audio, Walt Disney, Marcelite Garner and Billy Bletcher reprise their roles as Mickey, Minnie and Pete, respectively, from the classic shorts.
• Throw It In!: Originally, Walt Disney's dialogue was supposed to be temporary for the animators to animate Mickey's mouth movements, until it was decided to add authenticity to the retro feel by putting it in the finished product.
• Two Voices, One Character:
  • Pete is primarily voiced by Billy Bletcher, while Will Ryan provided the character's non-recycled dialogue.
  • Marcelite Garner also returned to voice Minnie via archive audio, while the character's then-current voice actress Russi Taylor voiced her non-recycled lines.
