What movie was it that came out a few years back about an ancient human species that crashed on earth?

There was a movie a few years ago that was about an ancient alien (but human) species that colonized earth then abandoned it. The plot of the story was about a ship that crashed and was carrying both one of the human aliens and an alien dragon on it. It was set in a Norse area about 3000 b.c. It has been driving me crazy because I can't remember the name of the movie and despite researching it, I have been unable to figure it out. Any help would be appreciated. Thanks.
