With Fred Williamson as director and star of Mr. Mean, is there any question as to the identity of the title character? Williamson plays a former Cosa Nostra henchman who seeks greener pastures. Hiring himself out as a hit man, he immediately lands a job. His mission: wipe out his old boss. Filmed in Italy, Mr. Mean certainly fulfills audience expectations.
