The CG animated science fiction film Terra has already gathered a big cast, and yet still more names arrive. Luke Wilson, Amanda Peet, Dennis Quaid, Justin Long and Chris Evans have just signed up, adding to the already heaving cast of Evan Rachel Wood, Brian Cox, James Garner, Danny Glover, Rosanna Arquette, Ron Perlman and Danny Trejo.

Already it seems set to be a huge film, and all we really know is a little of the plot and a lot of the cast.

The story comes from the short film from 2003 called Terra by Aristomenis Tsirbas who is also directing this full length film, adapted by Evan Spiliotopoulos. It tells the story of an interplanetary war between a peaceful planet who are being invaded by humans who want to colonise it. Variety.

So it really is just the cast list so far that's astounding, and what a list it is. I think that makes Terra a film to keep an eye or two out for.
