Query: Really great movie

Yellow Sky is definitely a classic black and white western and well written and acted. Gregory Peck does a great job and plays his role well. Ann Baxter is also really wonderful in her part. Realism is added by the fact that she is not heavily made-up as was Marilyn Monroe in The River of No Return. Her natural and almost rugged look is refreshing. I especially like the ending and the good moral values that come out there. I highly recommend this movie.
