Centurion
directed by Neil Marshall and starring Michael Fassbender (Quintus Dias), Olga Kurylenko (Etain), Dominic West (General Virulus).

This is a well made but somewhat empty historical drama about the fate of the Roman Ninth Legion which disappeared in 2nd century Scotland, which was Pict country. Obvious parallels can be drawn with Afghanistan. The Picts rarely stand and fight but rely on hit and run guerrilla tactics, assassinations, and nighttime raids.

Centurion Quintus Dias was captured by the Picts but escapes and hooks up with the Ninth Legion, led by General Virulus, who has received orders to take the offensive and deal with the Picts for once and for all. The general is guided across the terrain by a beautiful, deadly and mute Pict woman, Etain.

Of course things don't go quite as the Romans plan and Dias and a few desperate and disparate survivors of the Legion (native Romans, Franks, Numidians, Syrians, etc) have to make their way south while pursued by a deadly incarnation of Pictish (and female) vengeance. It was reminiscent of the movie The Warriors, which was of course itself based on classical sources.

This was shot on location in Scotland I believe and it was a really beautiful backdrop for the movie. The hills, moors, valleys and rivers were magnificent. If nothing else this was a great advertisement to visit.

Kurylenko was evidently a Bond girl in Quantum of Solace but I don't remember her. She made much more of an impression here.
Also Fassbender was in 300 and Inglorious Basterds (there was a deliberate (??) reference to IB where people hide under flooring from someone who would very much like to see them bleed).

The battle scenes are not like 300. They are shot more quickly and would look more natural were it not for the digitized blood.
If you like chase movies or historical films, you'll enjoy this. If swords and battle films bore you, this isn't for you.
Available on demand.

Edit: Like most good chase movies the film has a Tired of Running scene that works quite effectively.
