In Outlander(2008), Jim Caviezel plays "Kainan", an alien soldier whose ship crash lands on 8th century Earth in a Scandanavian lake. Kainan accesses his ships' computer log, learns where he is and then has a run in with the local clan of vikings. Kainan reveals to his Norsemen captors that he didn't arrive alone. In fact, a monstrous creature Kainan calls a "Moorwen" has tagged along on his spacecraft and is currently making itself right at home, slaughtering many of the locals as it does.
Kainan and the vikings must quickly work together to stop the threat of the "Moorwen", a hulking and four legged creature that emits a red-purple glow and has a nasty disposition.
I won't call this film spectacular but it's solid with decent special effects, a cool looking monster and Jim Caviezel's performance as "Kainan".
This movie can be bought on DVD and/or Blu Ray and is for sale at Amazon.
