These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Executive Meddling: Well, distributor meddling. The film originally used "Imagine" by John Lennon as background music to what sort of civilization would be created by a society that had shoved religion aside. The footage it backed was of Soviet Russia. Yoko Ono disapproved of this use of John's music and sued for infringement. It was ultimately declared fair use, but the video distributor cut the offending footage from the DVD, anyway.
