David Denby on Stanley Kubrick’s satirical masterpiece “Dr. Strangelove,” which is now a half century old:

“Why should a popular artist have any obligation to propose ‘sane’ solutions to an intolerable situation? Surely it’s enough to expose with overwhelming comic energy the contradictions and paradoxes of ‘mutual assured destruction.’ Sane actions are the business of scientists, the military, and Presidents, a few of whom may have been roused to act by this movie.”
