Spanish-language director Gonzalo Lopez-Gallego (El rey de la montana aka King of the Hill) has stepped in to replace Trevor Cawood as the helmer of the Weinstein Co.’s sci-fi “found footage” project Apollo 18. Cawood is the latest victim swept up in the space race to launch Apollo 18, which since its announcement at the American Film Market, has caused tremors in the burgeoning genre of “found footage” movies. It first caused Roland Emmerich to scrap his ultra-low budget sci-fi project The Zone, and then days later Warner Bros. dropped Dark Moon, a spec it bought concerning the Apollo moon missions to be directed in the found footage format by Olantunde Osunsanmi. Dark Castle then swept in to save it. Apollo 18 is being produced by Timur Bekmambetov and was written by Brian Miller, a winner of a screenplay contest founded by the Wanted filmmaker. The plan is to have this in theaters by March 4, 2011.
