Spin City star Michael J Fox has been honoured with a star on the Hollywood Walk of Fame.
"Acting is a great thing to do for a living, to do something you love, and to hear all the time that maybe you've done something to make people happy," he said at the unveiling. "It's no more than that and it's no less than that. It's just that, and it's great."
The Canadian-born actor, who rose to fame in the 80s with the Back To The Future films, has had Parkinson's disease for more than 10 years now and spends most of his time campaigning to help other people stricken with the illness.
He still does some acting work, however, mostly dubbing for cartoon movies such as Stuart Little and Atlantis.
He first realised he had Parkinson's in 1991 when he found he could not stop tremors that had developed in his hands. At first he was dismayed by the diagnosis and turned to alcohol for comfort, nearly destroying his marriage in the process.
He decided to fight on, however, and set up a foundation to help others with the degenerative condition. He also appeared before Congress along with fellow-sufferer Muhammad Ali, in a bid to win more funding for research.
