Michael J. Fox, the star of the "Back to the Future" films who is battling Parkinson's disease, will reprise his guest role on the "Good Wife," CBS' hit legal drama series.

His appearance comes day after he was honored with the Golden Camera award in Germany for his life's work.

Fox, a 49-year-old five-time Emmy winner, played cynical litigator Louis Canning on a "Good Wife" episode that aired in November. He faced off against main character Alicia, played by Julianna Margulies, in a massive class action. On Tuesday, Fox will appear on the series again. Warning: Spoiler alert!

In the new episode, set to air on Tuesday, Alicia races against Canning to round up the most clients for an Erin Brockovich-style class action lawsuit, while a mole is detected in the law firm who seems to be working for Canning, according to CBS.

Fox rose to fame playing Republican student activist Alex P. Keaton in the 1980s comedy series "Family Ties," which earned him one of his Emmys, and teenager Marty McFly in "Back to the Future," a cult 1980s science fiction film trilogy.

Fox was diagnosed with Parkinson's disease when he was about 30. He takes medication to alleviate his symptoms, which include tremors. Despite his ailment, he has continued his acting career, but has not taken on large roles. In recent years, he has had recurring roles on the drama show "Boston Legal" and on the firefighter drama series "Rescue Me."
