Pictures has picked up the rights to bring anime classic "Robotech," which featured giant robots known as mechas, to the big screen. Maguire is producing through his Maguire Entertainment banner and is eyeing the lead role in what the studio plans on being a tentpole sci-fi franchise."We are very excited to bring 'Robotech' to the big screen," Maguire said. "There is a rich mythology that will be a great foundation for a sophisticated, smart and entertaining film."Drew Crevello also is producing through his Supercool Hollywood BigTime Prods. Craig Zahler ("The Brigands of Rattleborge") has been tapped to write the screenplay."Robotech" was a cartoon series during the 1980s from Harmony Gold USA and Tatsunoko Prods. It was re-edited and re-dialogued to combine three Japanese anime series to give the producers enough episodes to air as a daily syndicated series.
