Most of the Clue fan pages are gone. The few that remain haven't been updated in years. It rather makes sense though, the movie wasn't that popular, it's
almost 20 years old, and there wasn't anything special on the DVD. However, here are the other remaining sites of note that have information about the movie Clue.
