In the time waster Silent Warnings (2003), a nutbag survivalist in Oregon gets himself blown up real good while chasing aliens invading his remote farm.
So his cousin, just now graduating from college, rounds up five friends (three of which are supermodels) to clean up the inherited property, sell it, then probably buy drugs with which to get high.
These city hippies discover crop circles all over the farm’s cornfields and notice that everything is starting to smell electrical. Then there are the nightly visitations, abductions, then ultimately a confrontation with the aliens who are using crop circles as a means of transportation. A sort of Old McDonald Stargate, if you happen to be partially standing in a spot where the circles suddenly appear, you’re vertically cut in half, as illustrated with the Cuisinart-ing of one post-grad student.
By the time the sheriff arrives, everybody’s screaming and shooting at the aliens, neither of which are doing any good. Somebody figures out that iron is the only thing that’ll kill the spacey farmjackers. Once again, metal saves the day.
The aliens are digitally transposed into scenes and look like 1980s cartoon figures. I offered to put on an alien suit to scare the smug outta those thugs, but the movie’s producer said aliens don’t have beer guts. How the hell does he know? He ever been to Mars? I have. In fact I’m going there as soon as I gas up the ’ol Stargate.
