Is there such a thing as too much "Avatar?" James Cameron revealed in an interview that he ready to do not only an "Avatar 2," but also an "Avatar 3" and "Avatar 4." When might we star seeing these films? Well, that's the tricky part. Originally slated to be released in in 2014, the first sequel has been pushed to 2016. But there seems to be positive signs pointing to the start of production. Film star Sigourney Weaver said in an interview for her new USA show "Political Animals" that the cast might be starting to film at the end of this year. And all three films will be filmed back to back to back. Eventually there will be a lot of blue on theater screens near you.
