I saw the MM interview. Charlie walked out because he can't defend his position, except with stupidities like the cold dead hand comment. He was also a total ham as an actor.
That wasn't an interview, it was an attack.
And it was a real low point for Moore.
Charlie should have manned up and debated with Moore. But he can't, the script wasn't written for him to parrot, like in his movies.
Manned up?
What Moore did was ambush journalism. He said he was going to do one thing and did another.
He also didn't let Heston finish any of his answers.
That's not even "debate". That's badgering. And the appropriate way to deal with it is to walk away or respond in kind.
By the way, I like Michael Moore.
