This list won’t all be Christopher Nolan… he just directs great stoner movies. Interstellar is another great mind-bender. Almost tying 2001: A Space Odyssey on this list, Interstellar incorporated similar trippiness throughout the movie. 2001 left most of its intense tripping for the last 3o minutes. Existential, philosophical, whatever word you use, Interstellar makes you think.
In addition to questioning the purpose of your entire existence, Interstellar is also an incredibly beautiful movie. From the wormhole scene to the tidal wave to the other side of the bookshelf, this movie will totally enhance your mental high as well as your visual high. I can promise you, the conversations with your fellow stoned movie watchers will continue long after this 3-hour movie ends.
