Ultimate Movie Site has launched their new website, a one-stop resource for everything movies. Constellation Framework is used to explore the relationships between films and actors. All the integration and customization was done by the folks at Ultimate Movie Site so check out their excellent work.
Gotta love how it starts you off with Kevin Bacon. (what?)
They also simultaneously released a Facebook application, Movie Degrees, which is used to explore your friends' favorite movies.
Each users' movie list is loaded from Ultimate Movie Site if available, or parsed from Facebook's "info" tab. Once you've chosen your top ten, you can click around and find out which movies your friends like.
Customizations to this application were done by Asterisq and more updates are on the way.
