Jenny is played by Charles Schulz's daughter Jill.
Due to negative reception from critics and audiences alike this TV movie has yet to be reissued on any form as of 2010.
Near the end, after Jenny asks Jeff what they are going to do and Jeff gets in the truck, their voices are obviously dubbed over by their respective actors as there was no microphone in the truck.
This was intended to be released around March 1988, but was delayed until September 1988 due to the release of Who Framed Roger Rabbit (1988) in June 1988 due to certain themes of theirs (specifically themes similar to each other).
