Cliffhanger

Probably everyone of my generation remembers a certain Disney film about lemmings where we see them throwing themselves off a cliff, plunging to their deaths. As a result we grew up thinking that Lemmings did that sort of thing. Except the film-makers 'faked' it. They threw the lemmings off the cliff and then edited to look as if the lemmings did it themselves.

I wonder if Disney was involved in this.
