Fox A Big Cheese In "Stuart Little 2"

Despite his well-publicized battle with Parkinson's disease, Michael J. Fox is still making movies; he again provides the voice for the little mouse with the big heart in "Stuart Little 2." He visits The Early Show to discuss his new role.

Fox is the voice behind the computer-animated mouse that just happens to have real humans as its adoptive parents. The film's big box office opening last weekend proved that the sequel to "Stuart Little" is as popular as the original.

An actor since he was 15, Fox has grown up in the public eye, first as the young Republican son in the Keaton family on "Family Ties" and later in films like "Back to the Future," which was the top-grossing movie of 1985.

It was while Fox was filming "Doc Hollywood" that he noticed an inexplicable twitching in his pinky, but it wasn't until a year later, in 1991, that he was diagnosed with Parkinson's Disease. He was only 30.

He concealed his illness and continued to work both in film and on television, landing a star part on the now canceled "Spin City." He won three consecutive Golden Globes and an Emmy as best actor in a comedy series for his role as New York's deputy mayor.

By 1998, his Parkinson's had advanced so that it was increasingly difficult to hide. He gave up his role on "Spin City" and dedicated his time to raising money and lobbying Congress on behalf of finding a cure for Parkinson's.

He recently penned a book about this struggle called "Lucky Man." In his book, he emphasizes the importance of the support of his wife, actress Tracy Pollan, with whom he has four children.
