Richard Brooks' gritty look at life inside the inner-city high school stars Glenn Ford as the earnest teacher determined to reach his students. Initially treated with bruising disrespect, the teacher works hard to earn the trust of his most troubled (and troubling) pupils─including the promising but embittered young man played by Sidney Poitier. Anne Francis, Vic Morrow, and Louis Calhern co-star; soundtrack includes historic film debut of "Rock Around the Clock." 100 min. Widescreen (Enhanced); Soundtracks: English Dolby Digital mono, French Dolby Digital mono; Subtitles: English, French, Spanish; audio commentary; bonus short "Blackboard Jumble" (1957); theatrical trailer.
