[**Outlander** (2008)][2]

> In 709 AD, in the Iron Age, a spacecraft crashes in the Viking kingdom
> of Herot, Norway, and the pilot Kainan survives. He turns the beacon
> on; learns the language and culture of the planet using a machine; and
> finds that the predator, Moorwen, that he was transporting, had
> escaped. While chasing the alien monster, he finds a village
> completely destroyed and is arrested by the warrior Wulfric, believing
> that he killed the locals - Kainan is brought to Herot as a prisoner.

From [this][3] page, the details you mentioned:

> Kainan's people came to the Moorwens' world to establish a colony,
> killing the natives and claiming the planet for themselves. As a
> reward, Kainan's wife and son were given a home in the new colony,
> while Kainan and the armed forces left for other conquests. Later, one
> surviving Moorwen slaughters all the colonists, including Kainan's
> family. Kainan was dispatched to capture the beast and was returning
> with it to his homeworld when it broke free and caused the crash.
