JM Barrie's own sci-fi story, Mary Rose, about a girl who vanishes for decades, then turns up still fresh and young as an overnight daisy, is also about getting a "second chance" in life. Tarkovsky's film made rather more of national melancholia and love of Mother Russia than it did of grieving over dead wives: understandable, as its troublesome director was about to be ordered to choose between self-exile or the Gulag.
