Inevitable after I read the book. Also some (director) Sidney Lumet and (President) Henry Fonda completism.
This adaptation is a bit too earnest, insufficiently rueful, too black-and-white; it's very east coast. It took me two sittings to get through. The capsule biographies are mostly gone, and Walter Matthau's grotesque Dr. Groeteschele also lost his sex scene with Nancy Berg. Single Side Band! — what is this, the 1960s? Many events are relayed by writing scrolling past on the Big Board, silently, which is tedious. The plot strikes me as too holey now; the Standard Operating Procedure seems undercooked and there's no believable reason for all the delays and lack of cross-checking. It's a long way from here to Primary Colours for Larry Hagman. Overall not a patch on Dr. Strangelove.
