Doors, The Easter Egg - The Lizard's Whisper

In one of the opening scenes of the movie, a young Jim Morrison is hitchhiking. Just after a car stops and he picks up his bag to get in, the camera pans across the ground to a lizard which whispers the word, 'Morrison'. You can hear the whisper again in the cave after the peyote scene in the desert (while 'The End' is beginning).
