During the "pool party" scene the plastic lei that Mitch is wearing goes from red to blue and back again.
The synopsis on the back of the most recent DVD version differs significantly from the original VHS, especially with regards to a mistake as to Mitch's age. It reads, "Mitch" (Gabe Jarret) is the 16-year-old wiz kid..." Mitch was 15-years-old as was actor Gabe Jarret when the movie was released (born Jan. 1 1970).
