Lemmings are not suicidal! Filmmakers in Disney's 1958 nature film, "White Wilderness" pushed dozens of lemmings off a cliff while cameras rolled, for dramatic effect—thereby staging a lemming death plunge. This deliberate fraud started the myth.
Finding it difficult to fathom that Disney would ever release a film that wasn't the gospel truth, the Oracle Google was consulted. Google clearly backs up the Farmer's Almanac on outing this fraudulent film. Amazing. How come I never knew this?
