Forest Whitaker's character in "The Butler” represents several generations of white house butlers, specifically inspired by a Washington Post profile of Eugene Allen, who worked in the White House from Harry Truman's administration to Ronald Reagan's.
As in the movie, the Reagans invited Allen and his wife to a state dinner.
Eugene Allen’s second cousin, Calvin Scott, owns a barber shop on Lake Arbor Way in Largo, Md.
Calvin Scott will regale anyone who needs a haircut with tales of his famous relative, just as hundreds of others in town remember their relations who also served.
The movie does not precisely present Allen's biography but rather uses the character of a butler as eyewitness to the civil rights struggle from the 50's to present day.
