Blacklisted screenwriter Dalton Trumbo wasn't listed in the original film's credits. Anthony Mann, who helped direct, was also uncredited. This epic film is one of my 10 favorites. It is rich in history, character development, action, romance, and human drama. It depicts man's inhumanity to man, but also shows how man can rise above insurmountable obstacles.
Few movies can boast of so many fine actors in one film.
This film is a true classic, well worth seeing again and again. Part of my personal DVD collection.
