Coollector

(which stays up-to-date via the Internet). What you do have to include manually (if you want to) are details like the type of support, the audio track and subtitle language(s), and film duration or location. Coollector's film entries are quite comprehensive. In them you'll find details on the plot and actors, ratings, and a few links where you can view trailers and official videos for each film (via PicLens).
