Sam Elliott
People in here are talking as tho Selleck is the greatest current portrayer of a cowboy. Permit me to draw to their attention--Sam Elliott. Elliott naturally has the laconic way of moving for a cowpoke & doesn't have to 'do' a voice--like Selleck does. Elliott naturally has the slow, deep drawl of a Texan. Both his parents were from Texas, tho he was born in California.
They've played brothers in 2 TV films--'the Sacketts' & 'the Shadow Riders'. They have both independently starred in adaptions of Louis L'amour books.
Not knocking Selleck, in any way. I LOVE him in westerns. LOVED 'Quigley'!
I just want to say that Elliott, in my opinion, is the more natural purveyor of the cowboy mystique. To be fair to Selleck--Elliott doesn't play a modern man as well as Selleck.
