Battle for Terra

Battle for Terra, originally screened as Terra, is a 2007 American 3D computer animated actionadventure science fiction drama thriller film, based on a short film of the same name about a peaceful alien planet which faces destruction from colonization by the displaced remainder of the human race. The film was directed by Aristomenis Tsirbas who conceived it as a hardedged live action feature with photoreal ComputerGenerated Imagery CGI environments. The close collaboration with producing partner and investor Snoot Entertainment redirected the project to become fully animated and appeal to younger audiences. The film features the voices of Evan Rachel Wood, Brian Cox, Luke Wilson, Amanda Peet, Dennis Quaid and Justin Long among others. It premiered on September 8, 2007 at the Toronto International Film Festival. It was widely released in the United States on May 1, 2009. The film was originally shot in 2D but was made in such a way that a second camera could be added to the film. After the film was shown at festivals and distributors showed an interest in it a small team was hired to render the entire film again from the perspective of the second camera for a true 3D effect. It won the Grand Prize for Best Animated Feature at the 2008 Ottawa International Animation Festival.

One day a large, mysterious object blocks the Terrian sun, piquing the Terrians interest. However, since the Terrian culture bans the development of new technologies, such as telescopes, without the approval of the ruling council, none of the inhabitants are able to get a closer look at the huge object in their sky.Mala, who is inventive and headstrong, goes against the rules of her community and creates a telescope, which she takes out into the dark empty area outside the Terrian city and uses to view the object and witnesses smaller objects coming from the large object that turn out to be incoming scout spaceships. She returns to the city to find that the scout spaceships have already started abducting Terrians who willingly offer themselves to the scout spaceships mistaking them as their new gods. ........
