Idea Regarding Actors and Directors for DVDs

When adding a DVD it appears to get it's actor and director selections from Amazon and the full cast never appears. Whereas the movies seem to get their actor selection from IMDB which is typically a full cast showing. In order to have a more clear view of which actors one has collected the most on DVDs...my idea is to maybe have the cast that appears with a movie show under the DVD section as well. Is that anywhere within the realm of possibilities?
