Here it is, the definitive catalogue of films spanning the history of the medium, from its birth in the silents to last week's releases. If you want plot summaries without spoilers, actor biographies, quotable quotes, and Academy Awards listings, then this is the place to start. But nearly everything here is linked to even more listings, so when you look up your favorite flick, you could stumble upon tidbits about the production company, any alternate titles or versions, details about the ratings system, cuts, and just about everything else. An extensive FAQ and help files are also included.
