Forest Whitaker as "The Butler" who served through eight Presidential terms (have fun trying to identify the well known actors who took those roles!) must surely win the Oscar! And Oprah Winfrey, as his wife, might easily take home her own statuette for supporting role.
"Lee Daniels' The Butler" is worth all the accolades it's been given. For me, however, the depiction of the racist discrimination and persecution of the Negroes back in the era of the Butler's early life in the South was so painful, so awful (and undoubtedly so accurate) that I left the theater horrified and deeply disturbed. (I spent my early childhood in Minnesota, where there were very few people of color. Then moved to California, in 1942 where I grew up, near Hollywood and Beverly Hills, a similarly "white" area.) The harsh reality of History is never pleasant, and often truly horrifying to see.
