Somewhat dated, MAGNUM FORCE is mostly a curiosity of sorts because you have future tv/movie stars (the late)Robert Urich (VEGAS,S.W.A.T), David Soul(STARSKY AND HUTCH), and Tim Matheson (ANIMAL HOUSE, 1941, WEST WING) in the villian roles (actor Kip Niven is the odd man out here who has went on to play mostly character support roles). The four play a quartet of vigilante mototcycle cops taking over when criminals buck the system and can't get convicted. Somehow, one wants to root for these guys, but when Harry Callahan (Clint Eastwood) refuses to support their cause and even join their crusade, it becomes a whole new ballgame. They begin to kill off members of their own police department who may get in their way and their toughest adversary, Harry Callahan is next on their list. As in the first DIRTY HARRY, the rule that everyone is protected by the law and have the right to exercise their rights as citizens is again explored with a twist. Eastwood again is great as the no nonsense Harry Callahan playing with him cool and tough. Again, as in all the 'Dirty Harry' films there is a classic line to be quoted. In this film, hands down, it's "A man's got to know his limitations!" Great villian role by Hal Holbrook as Lt. Briggs, good support role by unsung character actor Felton Perry (HOOPERMAN, ROBOCOP) as Smith..another one of Harry Callahan's luckless partners (in this reviewer's opinion, the film was a real downer when the character was 'oft' as a result of a letter bomb), and John Mitchum (brother of Robert Mitchum, F-TROOP, DIRTY HARRY, ENFORCER) as DiGorgio.
