The popular notion that lemmings in the wild commit mass suicide by leaping off cliffs is a sixty-five-year-old lie that has attained the status of myth. So says the Alaska Department of Fish and Game. The perpetrators were employees of the Disney Corporation in a 1950s documentary called White Wilderness. They staged the fake lemming migration with a combination of tight camera angles, judicious editing and a turntable, of all things. For the legendary cliff scene, they hurled lemmings into an Alberta river from off camera and captured them on film thrashing and drowning.
The reason? It made for good TV. Seriously.
