The second guy to play Gunsmoke‘s Matt Dillon — and the first on TV — was James Arness, also of note for his role in the original Thing, and for being sadly-also-dead Peter Graves‘ brother.

Arness died today, at 88.

(What I didn’t know: the first guy to play Dillon, who worked only on the radio version, was William Conrad, who later appeared in the 70s cop drama Cannon as well as the TV version of Nero Wolfe and as the latter character in Jake and the Fat Man.)
