Movie with vikings/warriors fighting an alien that looks like a wolf with tentacles

Question

I don't quite remember the setting but it seemed to be medieval or viking-ish. These warriors are dealing with a single monster that as I remember was wolf-like with tentacles coming out of its back, translucent and the tips of the tendrils glowed red. The group of warriors are slowly being picked off and sort of have a final stand to try and fight it or better off, kill it.

A spacecraft crashes in a lake in Vendel-era Scandinavia (550–790). The only surviving occupant – a humanoid alien – retrieves a distress beacon and a computer which explains that he is on Earth, a "seed" colony that his people have abandoned. The computer downloads the local Norse language and culture directly into his brain. The spaceman soon finds a recently destroyed village, where he is captured by Wulfric (Jack Huston), a warrior from another village.

Wulfric takes him to the fortified village of King Hrothgar (John Hurt), father of Freya (Sophia Myles), who he hopes will marry future king Wulfric. Hrothgar is concerned that Gunnar (Ron Perlman), chieftain of the destroyed village, will assume it was Wulfric's doing, as Wulfric's father (Hrothgar's predecessor) had been killed by Gunnar. Wulfric interrogates the "outlander", who identifies himself as Kainan (Jim Caviezel), claiming he is from the north, and states that he is hunting a dragon. The village is attacked that night by an unseen creature, which kills several men. Kainan identifies it as a "Moorwen", a predatory creature which caused his ship to crash and now will hunt men and animals alike. When Kainan is taken with a hunting party to find the Moorwen, he kills a gigantic bear that had slain some of the hunters, proving himself to the others who begin treating him as a part of their tribe.

Gunnar and his men attack the settlement, retreating, after both sides suffer casualties. They soon return, pursued by the Moorwen, and enter the safety of the village. Kainan devises a plan to build a huge pit just inside the village entrance, fill it with whale oil and leave wooden shields floating on the surface.

Freya becomes increasingly attracted to Kainan. He explains to her the Moorwen's origin—Kainan's people invaded its land (planet), slaughtered it in the billions and built a colony there. This Moorwen, now the last of its kind, massacred everyone in the colony, including Kainan's wife and child. When his "ship" returned to the colony, the Moorwen snuck onboard and later caused the crash. After listening to Kainan's tale, Freya gives him a family sword, saying she was told that she would know what man to give it to.
