Blooper: In the Disney version; an extra accidentally closes her nightgown into the door as she walks into her house.
Casting Gag: The Disney movie has Tommy Kirk play the toymaker's apprentice, Grumio, an aspiring Gadgeteer Genius. Kirk previously played a young inventor in The Shaggy Dog, and later played yet another one in The Misadventures of Merlin Jones and The Monkey's Uncle (with none other than Annette Funicello co-starring as his girlfriend).
Cut Song: The 1986 version was originally 150 minutes long when it aired on NBC, but was subsequently cut to 94 minutes for an overseas theatrical release. This is the version that was released on video and to TV syndication, and at least three songs were lost in the process.
The Danza: In the Disney version, Tom Piper is played by Tommy Sands.
Production Posse: Annette Funicello previously worked with Tommy Sands on The Parent Trap, when they sang two songs together (the title song and a pop version of "Let's Get Together"). This movie also marks neither the first nor the last time that she and Tommy Kirk would play major parts in the same movie.
What Could Have Been: The 1934 version was filmed on elaborately decorated sets with bright colors and well-made costumes. The studio chose to release it in black & white, disappointing many of the cast in the process. Modern colorized versions have tried to some degree to restore what could have been in the original release.
Every VHS, laserdisc, and DVD of the 1961 movie presents it in Pan and Scan. Only the Blu-Ray (the first Blu-Ray release of one of Walt Disney's live-action movies) and Digital HD versions show the movie in widescreen, although the case of the former says otherwise after removing the shrink wrap.
The "Mickey Mouse" appearance in the 1934 version (actually monkey in a costume) was officially approved of by Walt Disney as a favor to Hal Roach, despite the film not being made by Disney.
