Nicely crafted adventure yarn set in 1931. Anymore info and it would spoil the fun. Lee Marvin plays his role as a run-down lawman in a run-down Yukon trapping town with a tongue in cheek charm that he was known for in his later efforts. Add to this Charles Bronson doing his stoic loner and a great list of character actors (including William Sanderson) coupled with a tightly woven script, beautiful cinematography and some rousing action and you've got a neat little classic. Supposedly based on a true story, but whether it holds to the facts or not, who cares? Is it accurate? Maybe, maybe not. Is it a good movie? You bet! And in the end that is all that matters.
