Fox to Guest Star on 'Boston Legal'

Michael J. Fox (search), who left his "Spin City (search)" sitcom because of his fight against Parkinson's disease, will guest star on three episodes of "Boston Legal (search)" scheduled to air this season.

Fox will play a CEO battling stage-four lung cancer who hires Denny Crane ( William Shatner) and his associates to represent him in a lawsuit involving a promising anticancer drug, ABC announced Monday.

During one of his visits, Fox's character becomes involved with Denise Bauer ( Julie Bowen), one of the firm's lawyers.

"We couldn't be more excited. His comedic and dramatic strengths make him a natural for this series," creator and executive producer David E. Kelley said in a statement.

The Emmy-winning actor started the Michael J. Fox Foundation for Parkinson's Research after revealing in 1998 that he was battling the disease, a degenerative neurological disorder that affects movement.
