OMBD (open media database) is a free database for film media. There is no set editorial staff, but rather a large number of movie addicts and lovers who volunteer their time to provide material and develop the site. Anybody can add or change existing information on omdb once they have done the quick and simple task of signing up for their user login name. Films will thus be represented with equal opportunities hence Blockbusters, Soap Operas, and a college thesis film will each have their own place on omdb."
