The movie is as thought-provoking, in a less profound way, than Tarkovsky's "Solaris," another film about a sort of parallel Earth.
One of the most poignant moments in Andrei Tarkovsky's Solaris comes when the cosmonaut Snaut remarks that, “We don't want any more worlds, only a mirror to see our own.”
There are no little green men and no special effects to speak of, but the looming presence of that planet and its possibilities turns Another Earth into a metaphysical treat, with influences that range from Krzysztof Kieslowski's The Double Life of Veronique and Blue to Andrei Tarkovsky's Solaris.
First-time director Mike Cahill's "Another Earth" suggests Andrei Tarkovsky's "Solaris" by way of Aaron Katz.
