A year before directing Isaac Hayes in the violent yet breezy blaxploitation TRUCK TURNER, director Jonathan Kaplan put Jim Brown in prison for a more sparse and serious THE SLAMS, mostly taking place behind bars, and without relying on melodramatic prison tropes, since everything that goes down... from bullies to shiv-fights to mean guards... is tightly connected to the plot...
Where Jim Brown, an idealistic criminal from a groovy heist prologue, stole and hid loot from the mob, and, once in prison, a locked-up gangster hires gigantic convict Jack Cassady to attempt getting the formidable Brown to confess...
Making the more cerebral than physical, fast-talking prison captain Roland Bob Harris a far more effective villain (better than a typical tyrannical warden or henchman guard), connecting to Brown's newscaster girlfriend Judy Pace while working with pimp Paul Harris (also a pimp in TURNER), to either locate the money or plan a mutual escape...
And while the predictably safe and self-contained Jim Brown's tough enough from any interior adversary, Jonathan Kaplan's creative 70's-style direction keeps the suspense on par with the non-stop action.
