Tower is an animated documentary that tells the story of a massacre that happened 50 years ago and was a historic first: A man with no record of violence shot at people at random for no logical reason.
It was Aug. 1, 1966, in the middle of a 100-degree day at the University of Texas at Austin. The shots came from the clock tower at the center of the campus. A woman eight months pregnant was the first to fall, soon to be followed by her boyfriend and a boy delivering newspapers on his bicycle. It's not the usual subject for a cartoon.
