How about Ali?(2001)
The searchers,i am not really a western fan but this is a very good story.(1956)
On the waterfront,a classic i think.(1954)
Giant (1956)
The shootist(1976)John Wayne's last film.
Greystoke,the legend of tarzan of the ape's(1984) one of my fav films.
I think all these films would be worthy of a spot on the list!.
