Mr Majestyk is one of three things :-
Either it's a slow burning action movie with the good guy being pushed till he breaks. an age old story but this is from the 70's
Or, it's an advert for the strength, speed and agility of the Ford Pick-up truck. Apparently it was, the following year.
It's still a great watch with the dependable Mr Bronson though, and I would recommend you get a viewing in before the inevitable Statham remake which will probably end up a combination of this and First Blood. Hmm, that sounds quite good "'Why you keep pushing my fackin' melons you slag!"
