Anna Marie de la Fuente Cinekid Festival, touted as the world’s largest festival for children’s film and media, opens October 20 at Pathé Amsterdam Noord with Beta Film’s “Benjamin Bat,” an animated musical adventure pic about a bat with nyctophobia. “Benjamin Bat” follows a timid bat whose fear of the dark (aka nyctophobia), makes him an oddity among his peers. They find his sensitivity and love for singing, an activity reserved for their bird enemies, baffling.
