Michael Keaton adopted the stage name "Keaton" to avoid confusion with the famous actor Michael Douglas.

His real name is Michael John Douglas, and when he started his career in the 1970s, the Screen Actors Guild (SAG) rules required unique professional names to prevent billing or credit mix-ups. Michael Douglas, son of Kirk Douglas and star of films like Wall Street , had already registered "Michael Douglas."

How He Chose "Keaton"

Keaton has shared that he picked the name casually from a phone book, thinking it "sounded reasonable"—not as a nod to silent film legend Buster Keaton, despite the common assumption. There was also a talk show host named Mike Douglas adding to the naming conflicts at the time.
