Based on a ’70s manga by Japanese master Osamu Tezuka, a bored writer’s affair with his beguiling young muse gets the live-action treatment in “Tezuka’s Barbara.” Primarily concerned with the story’s excursions into erotic surrealism and the occult while playing down its social and political themes, this handsomely packaged item isn’t deep or meaningful but does present a visually arresting account of middle-aged male ennui colliding with uninhibited and irresistible female energy. Sure to be welcomed by Tezuka’s large fan base in Japan, “Barbara” has enjoyed a lengthy festival run since bowing in competition at the Tokyo Film Festival.
