Trivia, insights & behind the scenes
Inspired the 2004 'Killdozer' incident where Marvin Heemeyer armored a bulldozer and rampaged through Granby, Colorado—making this film weirdly prophetic.
Based on a 1944 Theodore Sturgeon short story; the TV movie was produced by Universal but buried in obscurity until internet irony resurrected it.
