“The Way Back” depicts the efforts of a young Polish man sentenced to 20 years for espionage who treks across Siberia with a motley band of inmates, including Zoran (Dragos Bucur), a cynical American who calls himself “Mr. Smith” (Ed Harris) and a tattooed gangster named Valka (Colin Farrell). With a bounty on their heads, they soldier through a gauntlet of endurance challenges encountering all manner of physical hardships. (Dir. Peter Weir)
