From Andreas Hartl:
Andy's Movie Database helps you to keep track of your DVD/movie collection. It's design is lightweight and minimalist, but it keeps track of the most important movie data (title, year, length, director, actors, genre, language, description, personal notes, etc.) and supports ordering, filtering and searching by these attributes or combinations: for example, you can quickly search for "all action movies that are longer than 120 minutes and are starring Bruce Willis". Automatic movie data import is also supported.
