Internet Movie DatabaseAn online database of information related to movies, actors, television shows, production crew personnel, video games, and most recently, fictional characters featured in visual entertainment media.
Basic information is searchable from any web browser. More in depth information is available on their paid subscription site, IMDB Pro.
While IMDb has come to be recognized as the world's most comprehensive source of film data, many non-contributing users are unaware of the means by which information is added to the database. IMDb essentially accepts data submissions from any individual who acquires a login and submits information using the site's submission pages.
This information is then reviewed by an IMDb data manager, who decides whether or not 1.) to post the information on the website; 2.) to send the submitting party an email requesting further documentation or clarification; or 3.) to ignore or set the submission aside indefinitely.
