Breakdown on AllMovie

Low-budget Realart Films managed to pick up an above-average property when it secured the screen rights to the Robert Abel play The Samson Slasher. Retitled Breakdown, the story concerns a heavyweight boxer, played by William Bishop. Framed for murder, Bishop is sent to prison, but is released after a few years on good behavior. Putting two and two together (no mean feat when you're wearing boxing gloves), Bishop surmises that the real killer is linked up in some way with his girl friend Anne Gwynne. Richard Benedict, a real-life boxer who turned actor in the mid-1940s, appears in the supporting cast as "Punchy."
