When small-town educator Bert Cates breaks the law and is jailed for teaching Darwin's theory of evolution, the stage is set for a dramatic courtroom face-off between prosecution-retained political lion Matthew Anderson Brady (Fredric March) and cagey defense counsel Henry Drummond (Spencer Tracy). Stanley Kramer’s memorable take on the Scopes "monkey" trial-inspired stage play by Jerome Lawrence and Robert E. Lee co-stars Gene Kelly, Dick York, Harry Morgan, Florence Eldridge. 128 min. Widescreen; Soundtrack: English; Subtitles: English; audio commentary; theatrical trailer.
