Filmaster, a project started by two Polish movie addicts in 2008 has made moves that could catapult them into the big marquee. Filmaster takes it one step further than movie databases like IMDB and movie recommendation engines like Mombo by combining movies and recommendation with a complete community-based social experience. And to support all this, it has a website, mobile applications and a Filmaster API to fuel further adoption.
Perhaps you're wondering which movie to see tonight? You could ask your friends on Twitter, or you could use Fflick to find out what they've already said. Fflick is a social movie review site, where the reviews come in bite-sized pieces from Twitter. The way its developers combine the reviews with other APIs and visuals shows how an excellent site can be built by bringing in content from elsewhere.
The self-proclaimed movie freaks behind MovieClips now have a platform that could allow for some really fun mashups. Unfortunately, even the most basic documentation is hidden behind an application form and a promise that "access to the API is granted only to approved partners."
