Outlander

Outlander has nothing to do with the outer space western Outland (Sean Connery from 1981) or the immortality tale inherent in Highlander. A pure genre piece Outlander mixes 8th century Vikings in battle with a monster (the Moorwen) from beyond our galaxy that has crash landed, along with other worldy astronaut Jim Cavieziel in their neck of the woods.
There's bits and nibbles of other films, maybe a dash of Planet of the Apes, a touch of Beowulf, but for the most part Outlander is its own animal. There would be an urge to shrug off the whole cheeseball affair but the filmmakers go the extra mile regarding sets, effects, costumes, and supporting actors, to give Outlander the kind of science fiction coolness that's hinted at on the covers of Ace double sci-fi paperbacks from the 50s or the fantasy writings of Robert E. Howard.
Part of Outlander's unlikely charm exudes from Sophia Myles playing the fair Viking lass Freya, and John Hurt's authoritative turn as the Viking king Rothgar. Not surprisingly Ron Peralman pops up and an actor I've never heard of, Jack Huston a kind of non-fey Russell Brand, plays an alpha Viking named Wulfric. The monster effects, while not ground breaking, are handled with the good sense to keep the beast in the dark.
