THE BOX is a clever and diverting little film. I am NOT trying to say it was bad--it isn't. However, I am surprised that it won the Oscar for Best Animated Short, though the 1960s were not exactly a banner decade for animation. The older style cartoons with beautiful backgrounds and high cel counts were pretty much a thing of the past by 1960 and the films nominated for Oscars throughout the decade were minimalist in nature--stark or non-existent backgrounds, low cel counts (instead of 24 cels per second, most were less than half of that--resulting in less fluidity of movement).
As for THE BOX, it's a very simple film with a very simple idea. A cute but scruffy looking older man comes out of the rain and enters a bar with a small black box. A guy sits next to him and wants to see what's inside, but the man with the box isn't about to let just anyone see what he's got. The idea goes from there to include a few other patrons and it is cute though not especially memorable.
