The Academy Museum of Motion Pictures is finally opening its doors in Los Angeles in April with an exhibit celebrating the works of the legendary Japanese animator Hayao Miyazaki. Envisioned as a journey through his six-decade career, it’s the first of its kind in North America and will have over 300 objects on display, organizers said Thursday. “Miyazaki’s genius is his power of remembering what he sees,” said Studio Ghibli co-founder Toshio Suzuki. Visitors will enter the temporary exhibit, which is organized thematically into seven sections, following Mei, the four-year-old heroine of “My Neighbor Totoro,” into the “Tree Tunnel” gallery. The museum will also organize film screenings in Japanese and English.
