Viking

The echoes of "Solaris" (the 1972 original Tarkovsky, not the remake) are hardly coincidental. The crew's moodiness, the claustrophobic interiors, and the "low-budget" effects here match those of the Russian masterpiece. That same year saw the cult classic "Silent Running" by the ingenious Trumbull, the guy who created the effects for "2001: A Space Odyssey". The notion of parallel worlds is a regular obsession in sci-fi and no less here, something Duncan Jones's "Moon" (2009) delved into with startling insights. For people who dislike unanswered questions and loopholes, this movie is not for you. It's part parable, part puzzle, part piss-take. Seriously unserious and vice-versa.
