Although I think that the original inspiration for the McCloud series came from Clint Eastwood's film Coogan's Bluff which involved a New Mexico sheriff in New York, Dennis Weaver certainly made Marshal Sam McCloud his own character and certainly was a lot less stiff than Eastwood's Joe Coogan.
The premise had Sam McCloud of Taos, New Mexico in New York to take some training in new law enforcement techniques. But it seemed that in every show he was teaching those New York City slickers a thing or two about criminal apprehension.
He was the bane of the existence of Chief Clifford who was played by J.D. Cannon. Cannon looked like he was about to let an ulcer get the better of him in each show. A bit more patient was the NYPD babysitter Terry Carter who played Sergeant Joe Broadhurst. Weaver even got a little romance going with reporter Diana Muldaur. Weaver was good for scoops at least.
And there was McCloud's eternal catchphrase. Whenever the New Yorkers finally got whatever he was doing it was always "There Ya Go". Weaver was always springing country aphorisms which he had to translate.
Weaver really made this show click. He hated playing Chester in Gunsmoke, always thought he should have been the marshal.
I'd say he proved it with McCloud.
