Outlander (2009)

We get the arranged, unwanted marriage between the girl and the king's son, the girl's attraction to the mysterious newcomer and the hero asking the girl to stay behind so she doesn't get hurt. There's even a minor character who is introduced with a little speech about drinking mead, just so he can repeat the same speech 90 minutes later when he lies dying in the hero's arms (they're friends now, you see).

At any rate, James Caviezel (humorless, as usual) plays Kainan the alien; he learns the local dialect through the use of a machine, but there's no explanation as to why he looks exactly like an earthly human being. Sophia Myles plays the fiery girl, tough enough to join the battle (women's lib in the 8th century?).

Jack Huston plays Wulfric, the king's son, who at first hates the outlander, but comes to befriend him. Ron Perlman almost provides some humor as the leader of a rival Viking clan, and John Hurt is tragically subdued as the king. Occasionally, but not often enough, the movie veers into unintentional humor, but mostly it just snoozes along.
