"In film and video, the
ethical line between reality and artifice was
blurred long ago. [...]
Disney's 1958 White Wilderness taught a generation of
schoolchildren--and many adults--that lemmings commit mass suicide.
They don't. The filmmakers purchased about 1,000 of the small rodents
collected by Eskimo children and, in a scene that has become a wildlife
classic, drove the hapless critters over a cliff to their deaths."
