Not through RSS, but through Apple iCal. I picked up this tip today when getting caught up on my Jason Kottke reading. Open iCal, go to Calendar > Subscribe, and paste in this URL. You will never miss another movie release again.
Speaking of movie releases, I snuck away last week to see Revenge of the Sith. I am a huge episode IV through VI fan, and a huge critic of episodes I and II, but episode III was actually pretty good. The love scenes are laughable, and there were a couple of other scenes that actually made the audience groan (literally), but for the most part, I really enjoyed it. Have you seen it yet? If so, what did you think? If not, what are you waiting for?
