Mount up for action with Chris Hemsworth in this impressively staged real life war movie.

The Thor star saddles up as the leader of a dozen special forces soldiers who ride horseback into Afghanistan in the wake of the 9/11 attack on the twin towers.

It’s a covert operation, and with military intelligence being what it is, only one of them knows how to ride. 

With a forward operating base nicknamed The Alamo, this feels as if it’s a western armed with automatic rifles.

They’re on a mission to assist local warlord take a strategically important city. In the grand tradition of General Custer, they find themselves outnumbered 5000-1 and facing missile launchers and tanks.

There are shades of Lawrence of Arabia as Hemsworth leads the locals’ charge into battle, but he’s no Peter O’Toole and Danish director Nicolai Fuglsig is certainly no David Lean.

There’s probably a really good thaddle Thor joke in here somewhere, put I just can’t seem to find it.

Though the action scenes are bloodily effective, the pace never manages to gallop.
