Plot hole: When Dr Hubbard is speaking to Dr Andrews at the nuclear power plant, the bees invade the plant, which subsequently explodes. The explosion should have completely eliminated the swarm along with the plant.
The Swarm (1978)
1 plot hole
Directed by: Irwin Allen
Starring: Michael Caine, Richard Widmark, Richard Chamberlain, Katharine Ross
Continuity mistake: When a larger group of soldiers enter the compound at the beginning of the film, the door of the compound opens to let them inside in one shot, but in the next shot the door is closed and opens a second time.
Brad Crane: Are you endowing these bees with human motives? Like saving their fellow bees from captivity, or seeking revenge on Mankind?
General Thalius Slater: I always credit my enemy, no matter what he may be, with equal intelligence.
Trivia: Irwin Allen used 22 million bees in this movie. This is largest cast of live animals in a feature film.
