Denis Weaver played Chester in
Gunsmoke and then as the leading man of 70s series
McCloud (based on Clint's
Coogan character) He died of complications from cancer on Friday at his home in Colorado; he was 81.

I also remember his fine performance in the 1971 Spielberg picture
Duel, where he played the terrorised driver persued by crazed truck driver.

Very sad to hear he is no longer with us.
