Who? (1974)

For those like myself who enjoy films that fit into no particular genre, and would enjoy a scene like a silver-headed metal man happily driving a tractor, this thing may be for you. ROBO MAN, as it is known on the video box, is a pretty strange affair. It is actually more psychological cat and mouse game than anything else, with the poor, metal-headed guy caught in the middle. The movie intercuts scenes of Gould trying to pick the metal man's brain to find out if he is who he says he is/was, with scenes of Trevor Howard appearing to brainwash the same guy at an earlier date. The intriguing notion is that Gould has such respect for the ability of his perceived enemy (Howard), that NOTHING the metal man says will prove who he is to Gould. I left the movie uncertain whether Gould's stubbornness helped or harmed humanity.

Also, it may have been intentional, but Gould acts more robot-like than Mr. Metalhead. The performance of Metaldude is actually quite affecting. Kudos to Joe Bova.
