A classic horror film is out now on Criterion Collection, and it stars '70's icons Donald Sutherland and Julie Christie as a couple haunted (literally) by the death of their child, as they adjust to a new life in Venice. This is actually less of a horror movie than a psychological thriller, but the atmosphere and setting is still effectively creepy. For a long time it was actually most known for a graphic sex scene between Sutherland and Christie, but don't get too excited for that- it's a little tame now, looking back on it. The best part is the acting and the haunting imagery of the mysterious shadows of their little (ghost?) girl. It also has one of the best final scenes in any scary movie ever made.
