I was 5 when the Beatles' "A Hard Day's Night" was released, and my parents took us to see it at the drive-in. I remember thinking for a long time that it was a documentary. (I didn't know what a "documentary" was, but I thought the film was real, unscripted, and just a bunch of cameras following them around)
