Before murder hornets became a concern, there was THE SWARM! During the 1970s, this film served as one way for media outlets to frighten people. Surprisingly, when it was first released, the movie genuinely terrified audiences in a manner similar to how Jaws did upon its release. The killer bee swarms originating in South America—a product of cross-breeding African and Western Honeybees—had to compete with other pressing anxieties of the time: an impending global ice age and disasters at nuclear power plants, both of which also appeared briefly in this film. Regardless, the prevalent fear in 1978 revolved around bees, and Hollywood ensured that viewers understood the message: humanity was destructive, and nature would retaliate. However, viewed today, the movie is quite humorous, no better than the climate change-themed films produced by SyFy (now NBC). The film quickly moves beyond believability when train cars explode as they travel downhill, a nuclear plant detonates like an atomic bomb killing 36,000 people, or the military decides to burn Houston in a manner reminiscent of Sherman’s march on Atlanta—all despite the bee swarms not being contained within structures. The exaggerated premise that just two stings from these bees would be fatal is also far-fetched, even though scientists (a term frequently praised when it aligns with certain viewpoints) knew at the time that the level of toxin in this new bee strain was no more dangerous than that of an ordinary honeybee. Instead, the genuine worry stemmed from their aggressive tracking abilities and ruthless attacks compared to typical bees. Despite its flaws, the film boasts a strong cast, and most performances are decent. I did find Michael Caine’s tendency to shout and act dramatically throughout scenes distracting. There are numerous other illogical moments, such as Henry Fonda's character using himself as a test subject when he is uniquely qualified to develop a serum, or Michael Caine smashing a window to enter a building when people inside could have simply opened the door—all while bees were attacking the town and had easy access to everyone through the broken glass. Unlike other disaster films from that decade, The Swarm fails to present any real danger and is essentially just an annoying buzz in the audience's ear.
