There is one movie that those over 55 yeafrs have seen many times. It wasn't because we necessarily wanted to, but it was an annual event in the days before cable and satellite.
The Wizard of Oz
It came on at about the same time every year in the 70's. LA had probably the most channels available which probably amounted to 6 tv channels? It was when kids were so desperate for cartoons, they'd watch Davey and Goliath on Sunday mornings, before the religious programing. Anyway, The Wizard was something all kids knew about and watched because everything else seemed to suck in that timeslot.
