That looks a lot like the short M-92 used by jaguar hunter Sasha Siemel, but he had the std. lever, of course.
Hollywood copies itself a lot, so this rifle inspiring the one used by Connors isn't too surprising.
I think Connors played baseball before he acted. He was a big, hard-looking man who I think had a quick temper. As a kid, I sometimes thought how unlike he was physically from the smaller, quieter Audie Murphy, also a Western and detective actor. I wouldn't want to get on the bad side of either, but Murphy was the known killer in real life, inflicting many German casualties in WW II as he earned virtually every medal the US Army could award, inc. the Medal of Honor.
I tried one of those large loop levers once. I think it was at either the SHOT show or a gun show. I learned very quickly that'd I'd better stick to std. levers. I found that big one slower to operate and the spinning rifle could knock you in the head pretty easily, as someone noted above. It was purely a Hollywood thing intended to impress viewers. I could always operate a bolt action quicker than a lever actiion, anyway. And didn't have to worry about getting my finger caught on the trigger as the lever closed. Still, If I could afford a luxury gun that I didn't need, I'd like to buy a Model 92 in nice shape or a really good repro.
