Never mind that The Hunger Games got the third biggest opening ever along with several rave reviews, there are some fans who aren't happy.

Racist fans of the book by Suzanne Collins reportedly took to Twitter to vent their anger over an African-American girl being cast to play the character of Rue (played by Amandla Sternberg) in the film, according to Jezebel.

"Why does Rue have to be black," wrote one fan, whose Twitter page no longer exists. "Not gonna lie, kinda ruined the movie."

"Awkward moment when Rue is some black girl and not the innocent blonde girl you picture," wrote another user, whose account has also been deleted.

What's interesting is that the book actually describes Rue as having 'dark brown skin'.

The Hunger Games is the first of the trilogy written by Suzanne Collins, followed by Catching Fire and Mockingjay.

The Hunger Games is running in theatres now. For more on the racist Hunger Games tweets, head to Hunger Games Tweets, a Tumblr created to "expose the Hunger Games fans on Twitter who dare to call themselves fans yet don't know a damn thing about the books."
