I learned of this movie from a preshow for some spooky movie at a theater where they play classic videos along the theme of the movie during seating. A horror comedy starring… Tom Poston? The quirky old neighbor on like a dozen 80s/90s sitcoms? In a slasher comedy of errors? Well, why not? For one thing, apparently this is a remake nobody asked for, but I’m not burdened by the expectations of the 1932 movie, so I’ll probably enjoy it more than it was enjoyed at the time.
The Triffids are an iconic piece of science fiction. Any locomoting plants in sci-fi stories will inevitably be compared with them.
The full-color alien invasion horror movie aspect makes me think about Invasion of the Body Snatchers, but there doesn’t really seem to be much in common between “anyone near you could have been replaced by an alien” and “run from that twenty-foot tall walking plant”. If there’s an allegory for something in the public consciousness in the 60s here, I’m not sure what it would be.
