The Butler is based on the real-life story of Eugene Allen (played by Whitaker, who also starred in Good Morning Vietnam alongside Williams). Allen served as a butler in the White House under eight different administrations.

This won't be Williams' first time taking on the role of a former POTUS; in Night at the Museum, the comedian played Rough Rider Theodore Roosevelt.
