Here's a random one for you: In the 2010 direct-to-video adaptation of Jack and the Beanstalk, Christopher Lloyd stars as the Headmaster of a fairy tale school. In this version of the classic tale, Jack is a fairy tale character who must perform a heroic deed by Monday or he'll fail his fairy tale class. So Jack goes and pawns his Computer of Wonder for some magic beans that he uses to help recover a special harp from a Giant. The film didn't make a big splash (hence its straight-to-video premiere), but what this version of Jack and the Beanstalk does have is a random celebration of the 1980s.
First off, it stars 80's heroes like Chevy Chase, Katey Sagal, Gilbert Gottfried, Christopher Lloyd and Wallace Shawn. Also, in the scene where Jack is trying to pawn his Computer of Wonder, Wallace Shawn (who plays the pawn broker) offers Jack Iocane Powder at first. Fans of Shawn will remember that Iocane Powder was the same fictional powder that took out Wallace Shawn's character in The Princess Bride. That's easter egg number one.
Easter egg number two comes in the form of Lloyd, who during one scene is busy teaching his class while a number of Back to the Future references are scribbled up on the chalkboard. There's a drawing of the Flux Capacitor with a message underneath that reads, "Make A Note Of This!!" Also in the scene on another part of chalkboard is the note, "1.21 gigawatts!" See the images above, and check out the scene in question below.
This concludes today's lesson on "Random Back to the Future References in Other Movies." Good day.
