Little Big Soldier (2010)

Two armies clash in ancient war-torn China; none survive but a young general from a royal house and a farmer foot soldier who binds the fallen leader to take him home and claim a reward. Many stand in their way: an abandoned songstress, the noble's own murderous younger brother, desperate beggars, rough slavers, and the pair's own differing agendas. Through it all, a bond forms between the two, and what will happen at journey's end becomes anyone's guess.
