I just updated my Cloverfield post with some extra information after my earlier rewatching with the commentary track enabled. Matt Reeves shared an incredible amount of information about the making of the film and how they accomplished so much on a relatively modest budget. He explains that much of the dialogue was improvised or customized to fit the loose, documentary feel of the film better, and how Children of Men, United 93, and several older monster movies served as inspiration for this film.
I’m still buzzing about this film because I truly think it’s one of the better films made in recent years. Along with the more traditional but still awesome Star Trek—not to mention continued success with both Lost and Fringe—JJ Abrams definitely is on a hot streak with his productions lately.
