40 years ago this weekend National Lampoon’s Vacation held off Stephen King’s new release about a sweet dog that needed a bath, Cujo. But look at that lineup. Risky Business, Return of the Jedi, Staying Alive, Trading Places, Jaws 3D, WarGames, Krull, Mr. Mom, Flashdance and Valley Girl hanging on for 4 months. The movie theater was just different back then. You went and watched a movie, in the theater, multiple times. You never knew when you might see it again, unless you had HBO.
