It's odd that whenever talk of Prison base films crops up you rarely see Brubaker mentioned as a viable piece of work, which to me personally is a damn shame because it's origin source provides a worthy story to be involved in.
Based on the writings of Tom Murton, a Prison Farm Reform Warden in Arkansas in the late 60s, the corruption and murder the film deals with is a very frightening reality, and although this film is obviously fictionalised to a degree, the evidence of the main themes can be found from many sources.
Under 17 requires accompanying parent or adult guardian 21 or older. The parent/guardian is required to stay with the child under 17 through the entire movie, even if the parent gives the child/teenager permission to see the film alone. These films may contain strong profanity, graphic sexuality, nudity, strong violence, horror, gore, and strong drug use. A movie rated R for profanity often has more severe or frequent language than the PG-13 rating would permit. An R-rated movie may have more blood, gore, drug use, nudity, or graphic sexuality than a PG-13 movie would admit.
