I'm also looking for a British film that was about what you could do to survive an atomic bomb, but was just grimly honest about your chances. Something like "Bob and Linda built this refuge in their home using the instructions from an official pamphlet. They are protected from the light and heat, but at this distance from ground zero, that means that it will give them approximately three extra seconds of life until the blast wave hits." The anti-Duck and Cover, if you will. I can't remember the name.
