All the Ford/Wayne pics are the best IMHO...but if I had to narrow it down to 3 it would be, Quiet Man, Liberty Valance and The Searchers(I think my fav).....I'll check out Walmart and pick those two up, although after watching them again recently, they are not near as good as I remember them...
McQ is surprisingly good, but haven't seen Brannigan in so long I can't remember if it was good or bad.
