Check out this little gem. In 1974, a made for TV movie came out about a meteor that has a special power. This meteor is hit by a bulldozer, and then said meteor power is transferred to the bulldozer. This power basically makes the bulldozer "possessed", to the point where it now drives by itself and starts to kill people!!! This is no ordinary bulldozer.....no, this is KILLDOZER!!!!! This movie looks like it would be in the so bad it's good category!
