Amateur Cast: The kids are actually billed as "'Kids' from Ruth Foreman's Pied Piper Playhouse". (That's not a typo: "Kids" is in quotation marks in the credits.)
The Danza: All of the child actors are called by their real first name. Except for the three girls who are just called "girls."
Dawson Casting: Some of the "kids" are clearly pushing high school age. Also inverted as it's quite clear to the sharp-eyed viewer that the actor portraying Santa is much, much younger than he's intended to be under the quite obvious white stage-wool hair and beard (a moment of silence for that poor man's case of heat exhaustion).
Throw It In!: During the early scene of a kid with a raccoon, it's obvious the animal is freaking out with the boy desperately trying to improvise off it.
The Thumbelina adaptation contains examples of:
Acting for Two: Shay Garner plays both the title character and the young woman who stumbles upon the exhibit. The Thumbelina segments are presumably the young woman imagining the story as she listens to it.
The Jack and the Beanstalk adaptation contains examples of:
No Budget: The golden hen and magic harp are mocked up from tinfoil and the scenes with both Jack and the giant are painfully clearly made by projecting the giant on a movie screen that Jack's walking in front of.
Unintentional Period Piece: All the characters except Honest John and the giants wear contemporary (1970) clothing that's very much of its time. One suspects it's because they had to use the actors' own clothes.
