Second viewing. An important sci-fi film written by the authors of Tarkovsky's "Stalker" with Juri Jarvet, who starred in Tarkovsky's "Solaris" soon after his superb performance in Kozintsev's "King Lear." But in this film, it is actor Uldis Pucitis who is most impressive as the Police inspector. Important film for fans of Jarvet, the Strugatsky brothers' writings and sci-fi films
