The Swarm
The Swarm (1978) by Irwin Allen, starring Michael Caine, Katharine Ross, Richard Widmark, Olivia de Havilland, Henry Fonda, Fred MacMurray
Irwin Allen did quite a few disaster movies (The Poseidon Adventure, Airport) that were commercial, if not always critical, successes. The Swarm, in contract, was a flop both commercially and critically — and a massive waste of some very good acting talent as well.
