Burt Lancaster did 16 westerns, most a lot that were different where he played vastly different characters. Not just Duval acting like Gus in anything since the Dove, or Duke being Duke in most of his.
Lancaster also performed his own stunts.
Not saying he should be #1, or even top 5, but I'd find it hard to kick him of the list for somebody more popular, not necessarily better.
Even in
True Grit, Duval was just playing a younger version of Gus, personality and mannerism-wise.
