Wow, can't believe you resurrected this old post. I'm sure Klugman and Durning would smile at that.
It doesn't surprise me about how both Klugman and Randall behaved. I know Klugman was really just kind of an everyman, who liked to go to horse races and hang around with old pals. He was not a limelight guy. Tony on the other hand, as you say, loved it!! He was a ham. I used to watch him on Johnny Carson and man, you could just see the guy loved to tell stories and ham it up and eat up the crowds reaction. Not saying that in a bad way, just meaning he loved where he was and enjoyed the attention.
Durning was a funny guy. You know, fat, not a leading man type. But he had a certain charisma. When I watched him in a movie, I couldn't take my eyes off him. There was just something about that guy that got your attention. You can see why he was in so many films. He just had it going on. You're right, he was great in Tootsie and so many other films. I loved in Brother Where Art Thou when he played the Governor and walked past George Clooney and his idiot brothers and called them dumb crackers because they didn't know who he was. Just the way he said it. I grew up seeing him in so many films back in the seventies, many of them made back in the 60s too.
He was a REAL hero in WWII and experienced just horrific things that effected him his whole life and made him a staunch opponent of war. The guy was intelligent, kind, thoughtfull, introspective and not only loaded with talent, but bravery out the wazoo. He was a rare bird and such a treasure not only for those of us who loved his film career, but for the soldiers he fought with in WWII.
