There's a whole lot to like about the world's tiniest solar movie theater, including a mobile setup that brings the theater to you (at least if you're in the U.K.), a vast library of music videos and short films (many of them environmentally-themed), and bespoke ushers that channel Hollywood's Golden Age.

Why It Stands Out: This theater is exclusive – only allow for eight people to enjoy a show at any given time.
