A spider escapes from an isolated desert laboratory experimenting in giantism and grows to tremendous size as it wreaks havoc on the local inhabitants.
Classic 50s monster movie is still fun and in so many ways much better than its present-day clones.
On renewed view: I still enjoy this movie, one of the best B pictures ever, and a favourite from my childhood on.
Halliwell (no star): "Moderate monster hokum with the desert setting which became a cliche; the grotesque faces are more horrific than the spider, which seldom seems to touch the ground."
Maltin ***: "One of the best giant-insect films, with fast-pacing, convincing special effects, and interesting subplot detailing formula's effect on humans. That's Clint Eastwood as the jet squadron leader in final sequence."
