The Plants In Motion movies remind me of that episode. Since plant movement occurs much more slowly than movements we can easily observe, we tend to think that plants don't move. These movies prove that idea wrong. Filmed with time-lapse photography, these short movies show seeds germinating, beans dancing to circadian rhythms, twirling vines, flowers bursting out with passion, and many other activities that we simply don't see because they happen at a different rate.
I think a collection of these movies on a DVD, with a good soundtrack, could be a lot of fun. It wouldn't have quite the impact of Jumanji or Invasion of the Body Snatchers, but it still might inspire a deeper appreciation for the plants in our lives.
As for the background music, my vote goes to: "Feed me, Seymore!"
