Here's another title that's on the MIA list. "Killdozer" is an interesting little tale based a short story of late sci-fi writer Theodore Sturgeon. Very unusual that the setting of the story where this bulldozer runs amok is an island somewhere in South Africa. Too bad the movie doesn't go into detail about the strange force that possesses the machine and starts it on a murderous rampage. But watch for a very young Robert Urich - way before his stint on 'S.W.A.T.', 'Vegas' and 'Spenser; for Hire'. My mother and I enjoyed this movie along with others such as 'Duel'. There's a sub-plot to Clint Walker's character: trying to overcome his battle with the bottle which led to a certain fall from grace in the company he works for. One gets the impression that he was sent on this construction job as a sort of punishment. Much as I'd like to think all the vintage ABC programming is seared into my memory, it has been so long since I've seen this movie, I could be mistaken about one or two points.
Additional note: Clint Walker fans should also see another ABC movie title the actor did called 'Scream of The Wolf'.
