A great movie about how war can get out of hand very quickly. The book the movie was derived from "Trinity's Child" is EXCELLENT. It is ironic that the President was played by Martin Landau and in the book, the president was watching "Mission Impossible" when SAC HQ calls him. As you know, Martin Landau starred in "Mission Impossible. Also, James Earl Jones plays an Air Force SAC General in this movie. He also played an Air Force Lieutentant on board a B-52 in "Dr. Strangelove".
