From his hilarious role as young Republican Alex P. Keaton on "Family Ties" to hoverboard-riding Marty McFly in the "Back to the Future" films and then on his brave battle with Parkinson's disease, Michael J. Fox is generally regarded as a beloved man. But sometimes even a beloved man -- just wants to have some fun and play a "d--k" on TV.

Fox, who just nabbed his 17th Emmy nomination for his turn as the deliciously manipulative defense attorney Louis Canning in "The Good Wife," recently did an interview with The Hollywood Reporter in which the actor, who has been battling Parkinson's since 1991, said he wanted to play a character with a disability who wasn't a good guy.

The 55-year-old said of his guest-starring role, "I thought it might be interesting to have a kind of version of Parkinson's, maybe not Parkinson's explicitly, but dyskinesia, which is a side effect of it."

The pint-sized Canadian added, "We toyed with that idea, and they came up with that scene in the courtroom where I stand in front of the jury and say, 'You may see me move this way or that way' -- I think it kind of blew people away on the set that I would be so open with it, but I just knew this was a perfect opportunity to funnel a lot of my life experience into a character and be coy with it and kind of let it out in dribs and drabs and see if I can make it an effective tool for him to do his job, as opposed to something that prevented him from doing his job."

Fox also wanted to make sure he played a disabled character that wasn't a pushover or a goody goody.

The "Spin City" actor said, "It's funny because whenever a show or any representation of characters with disabilities on television tend to be sentimental with soft piano music playing in the background and I wanted to prove that disabled people can be a--holes too."

Fox, who guest starred on 26 episodes of the CBS drama added, "You want to feel sorry for him, but he's such a d--k whether intentionally or not. I think he's pure-hearted, I think he just wants to win and whatever may be seen as a deficit, he'll turn into an asset in order to prevail." Well -- we know Fox himself has prevailed despite his disease …

This past May "The Good Wife" ended after seven seasons -- and the ending wasn't very well received. Many fans were disappointed with the show's creators Michelle and Robert King's choices, but Fox told THR, "I thought it was perfect. I don't question Bob and Michelle. They always know the right note to begin and end."

Good point! Who wouldn't want to see Diane (Christine Baranski) slap Alicia (Juliana Marguiles)?!
