Writer Charlie Kaufman has come up with some pretty heavy premises in his time, but his best foray into the realms of the strange and bizarre came in 2004’s Eternal Sunshine of the Spotless Mind, a sci-fi romance story notable for its mind-bending plot and mesmerizing visual style. Jim Carrey and Kate Winslet star as Joel and Clementine, two former lovers whose dysfunctional relationship leads them to a technology company that specializes in erasing painful memories from subjects’ minds. This ingenious premise allows director Michel Gondry to really have some fun playing with time and space, and in some scenes objects and people will disappear out of the shot as they are systematically being erased from a character’s memory. All this makes for some amazing sequences, but what really makes Eternal Sunshine such a weird trip are all the questions it forces the viewers to ask themselves: are we nothing but the sum total of our memories? Would it be worth it to delete bad experiences from your mind even if you lost a little of yourself in the process? That kind of depth of subject matter is a rare find in movies, and it’s a big part of what makes this film such a strange and memorable experience.
