Although it tells a mildly fantastical tale of ghosts and a magical mansion, When Marnie Was There is best at capturing authentic childhood experience. Even the sound is right. Maybe it stands out because we’re watching an animated movie, but the ambient noise is uncannily good. When the heroine arrives at her new home for the summer, every creaky floorboard and tinkling wind-chime gives a feeling of “Yes, that’s exactly how that sounds.” Those things are felt more keenly when experienced in a new place, which is the situation for Anna. She’s been sent to the seaside by her frustrated adoptive mother, who suspects a change of scenery would benefit the shy girl. Anna stays with a kindly older couple, but her imagination is captured by the moody house across a tidal flat, where ethereal blonde Marnie offers friendship. (SIFF will screen both the original Japanese-language version, with subtitles, and the dubbed version, with Hailee Steinfeld as Anna and Kieran Shipka as Marnie.)
