What a waste of talent. The Swarm was an awful film full of plot holes, terrible dialogue and some poor acting. It is really odd to see Michael Caine in the film as everyone else is American. It just didn't seem to gel. The talent that is wasted in this film is astonishing. You've got Henry Fonda, Olivia DeHavilland, Richard Widmark, Fred MacMurray, just to name a few and to see them wasted with a such poor script especially Widmark, I don't know how he kept a straight face. This production is fairly typical of Irwin Allen. His TV series's, Lost in Space etc started well in their first few episodes then it was reduced to drivel. It is the same with his disaster films, they started out well, like the Poseidon Adventure, but by the time of the Swarm and When Time Ran Out, they were poor efforts, with bad scripts and a waste of good talent.
