Killdozer was (now cult) made for TV movie from the 1970's. Veteran actors play veteran construction crew clearing terrain for an oil company, on an remote island off coast of Africa, that come under attack by one of their own bulldozers.
Actually, the bulldozer (the mighty D-9'er) has been contaminated by some kind of malevolent meteorite radiation, and perhaps its mind, located in its shovel evidently, has turned murderously psychotic.
This after striking a rock with an early Robert Urich (Mac) at the controls. Urich succumbs soon after from the effects of a massive 'bangeroo' headache from the encounter.
Maybe, more spectacularly, Killdozer is being remotely controlled by extraterrestial forces as Dutch speculates. Actually, it's more likely that it is being controlled by Hollywood powers that be and conventions since it starts its murder spree by knocking off Beltrane, the only black guy in the cast. You won't know until the end!
Movies today try to look real, but movies like this, and its later (man vs machine) cousins, The Car and the classic Duel, share that 70's trademark of hardnosed grittiness and dedicated character studies, that make them at least FEEL real!
