This is a film about endurance in pretty dismal circumstances so if you are seeking laughs, thrills or excitement then you are going to be sorely disappointed. Escaping from a Soviet Gulag the heroes of this piece have to march through taiga, desert, mountain and just about everything in between; and they do so not by ingenious device or cunning plan but by putting one foot in front of the other for 4000 miles. I found it a stirring tale but then I liked moor-running at School so am probably deranged.
There has been some excitement about whether the story is true (it is based on Slavomir Rawicz's book): it didn't seem necessary to me that it was or was not true, but be warned if this does matter to you you may want to consider before watching. There is also some concern (sometimes by the same critics) that the central role is not more charismatic. This is however a film about walking which is of its very nature a slow and steady form of movement. It does not require a John Rambo or James Bond.
