Side by Side, the documentary A.O. Scott of The New York Times calls "Worth a year of film school and at least 1,000 hours of DVD bonus commentary," came out on DVD and Blu Ray today. Which reminds us of this great Side by Side outtake of Greta Gerwig and Keanu Reeves pondering the absurdities of processing digital film to make it look like celluloid.

By the way, what are you up to, Greta? We're not seeing any upcoming projects on your IMDB page, which hopefully means you have something really big in store...
