The 'Back to the Future' actor's close pal Denis Leary was jealous when Michael won an Emmy Award for guest starring on his TV show 'Rescue Me' but admitted he can't hold it against his friend because he is such a great person.

He told The Hollywood Reporter: "The only thing we won was for Michael J. Fox's guest role. I'm happy for him, but Mike's got, I'm guessing, four or five Emmys. So when you get to the point where one of your friends already has four Emmys, and you got him one of them, there's a greedy little part of me that's like, 'You know, I wouldn't mind having one.'"

"If he gets nominated and wins this year [for 'The Good Wife'], I'm going to his house and I'm stealing the Emmy from him. Like he needs another one! He also has, like, $600 billion in 'Spin City' money. I hate him. He's a talented guy and nice and successful. He's the worst kind of friend because he's actually the greatest human being alive. There is no way to look good standing next to him."

Michael - who was diagnosed in 1991 with Parkinson's disease, which affects the central nervous system - has previously said that working on 'The Good Wife' was a positive experience for him.

He explained: "Career wise, it was great to work again. That was really fun.

"I don't have the physical subtlety that I had before. I don't have the elasticity of expression that I had. But at the same time, this experience has given me a gravitas, a kind of steadiness and a stillness, even in my motion, that I didn't have before. It's really taught me how to be quiet."
