I may have something more substantive to say about this, but I'd like to clarify a detail in the Washington Post article: Jack Johnson's life and career were the basis for The Great White Hope, all right, but it was originally a play by Howard Sackler that premiered at our own Arena Stage in 1967, starring James Earl Jones and Jane Alexander. I saw it during its run there. The production later moved to Broadway with the same cast. A film adaptation was released in 1970, also starring Jones and Alexander.
