Howard Sackler’s Pulitzer Prize-winning play is a key work in the genre that one drama critic has defined once and for all as “middle seriousness”—e.g., The Elephant Man, Amadeus. This film version, directed by Martin Ritt, is plop in the middle too—provocative but never challenging. Mainly, this is James Earl Jones exercising his voice and Jane Alexander working her brow. With Lou Gilbert, Chester Morris, and Robert Webber (1970).
