According to the Hollywood Reporter, Warner Brothers has picked up the film rights to the gestalt anime franchise, and they'll be producing the film alongside "Spider-Man" actor Tobey Maguire. Maguire is also considering a lead role.
Although the article doesn't say specifically, the film will probably not span the entirety of the Robotech saga, itself combined from three Japanese anime properties ("Super Dimension Fortress Macross," "Super Dimension Cavalry Southern Cross," and "Genesis Climber Mospeada"). Given Maguire's physical specifications, he's likely eyeing the role of Rick Hunter (or "Hikaru Ichijyo" for all fans of the original "Super Dimension Fortress Macross" series), which is the section of the story most familiar with US audiences, called The First Robotech War.
Frank Agrama of rights-holder Harmony Gold will exec produce; Jason Netter will serve in a producer capacity. Matthew Reilly brought the project to Warners and is overseeing. Daniel Shafer brought the project to Maguire and will shepherd for the company.
This is seen as a response to the success of "Transformers" in cinemas, so giant robots are once again interesting to many Tinseltown players.
