Robotech the movie
I've always wondered why television and films about robots that join together and make one big robot always seemed to be made over Robotech, but perhaps the straight robot action of Transformers (Filmstalker review) had something to do with changing the minds of the studios, for now Warner Brothers have bought the rights to the series for a film version.
I loved the Robotech series which was from the eighties, a prime plundering point of Hollywood right now, it tells of a time when an alien spacecraft crashes on Earth and man exploits the technologies on board to create giant robots which turn into spacecraft (the logical thing you could see robots doing). It's about then that an alien race start attacking Earth and humans defend themselves with these new robots.
I think out of all the post-Transformers robot film talk that this might be the one that really offers any studio the biggest chance with a rich and potentially strong franchise. However that silly Voltron might well be in with a good chance, hey look, my robot animal can join with these other robot animals and make...another robot!
I have a lot more love for Robotech because it's more science fiction than the children's stories such as Voltron. I'd love to see it made and according to The Hollywood Reporter through IESB, that's exactly what's going to happen over at Warner Brothers.
