Leonard Maltin summons up a memory from his high school days: Sitting through all 15 chapters of the 1943 Batman movie serial at a theater.
They ran it in L.A. at a theater that used to be down on Western (or maybe it was Vermont) and I somehow got my father to take me to see it. It was one of the few unpleasant things I ever did to my father, ranking slightly ahead of the time when at age nine, I got carsick all over his trousers. Shortly after, he got even by taking me to see the world's longest production of Die Fledermaus, which in many ways was the same story except they sang it.
