"Avatar" has become the highest grossing movie of all time, which is why it comes as no surprise that a sequel will definitely happen. Director James Cameron has already said that most of the money that went into developing the first film will not have to be spent again since lots of the environments and effects have already been built.

Cameron added that it would be stupid not to make "Avatar 2." Now /Film is reporting that technical crew members have already signed on for a second installment. Their contracts are for three to five years, in case development runs long.

Judging by this news, it seems that "Avatar 2" will not be in theaters before 2013. That's a long time to make movie that already has a story and has most of the hard work already done.
