"Killdozer" is a very entertaining TV movie from 1974, telling the story of a construction crew on a remote island (that looks a lot like southern California). The men must fight for their lives against a huge bulldozer controlled by a murderous alien force. The silly premise is made watchable by a good cast, lots and lots of action, an intelligent screenplay, and fine (if TV-style) direction.
A D9 bulldozer strikes a strange-looking rock, whereupon a mysterious alien force (shown as a blue light) is transferred to the 'dozer. The big machine soon has a mind of its own, destroying the construction workers' camp and proceeding on an orgy of killing and destruction. Good acting work by Clint Walker, Carl Betz, and Neville Brand help uplift the proceedings. Watch for a very young (and skinny) Robert Urich, who only survives the first few minutes of the movie before being scorched by alien radiation. The other workers are methodically wiped out until only two are left.
The Killdozer does its homicidal work with much enthusiasm, revving its engine, emitting black diesel fumes, waving its huge blade, frantically moving its control levers, and flashing its lights. The climactic "Killdozer death scene" is pretty good, as Walker lures the violent 'dozer to its deathor at least the death of the alien force.
In summary, I think this film is very good but I have a few other items to discuss. I saw this movie 31 years ago, and I'm still wondering how a 50-ton machine with a roaring diesel engine which belches huge clouds of black smoke could possibly sneak up on and surprise anyone. But the Killdozer manages to do just that, much to the detriment of the workers. Another issue is the one lesson I learned from this movie: If a maniacal bulldozer controlled by an alien force is lurking aboutdon't get drunk.
