Have you seen the video on youtube of the bison who save their calf from the lions? Even though it was shot by an amateur on a safari, the scene plays out like a perfectly scripted vignette. Scene opens on lions. Bison enter stage left. Chase ensues. Tragedy! Sudden unexpected turn for the worse! I won't give away the dramatic climax, but even the way the "actors" exit "the stage" is oh so Hollwood! You have to watch this 8-minute video.
