Unless you're willing to concede that the the movie was made as a farce, which I don't happen to believe, then the plot and acting are one cringeworthy moment after another, starting with Janet Leigh's improbably striptease after landing her Soviet fighter at a US airbase, not that there's anything wrong with her stripping, of course. The improbabilities pile on higher and deeper to the point that being probable is no longer even the point and you just don't care anymore.
That said, the true star of this movie is the period hardware, some of it seldom seen anywhere else. The scene of the night interception of the Convair B-36 showed an early model in flight in such detail that if you look closely you can see that the retractable weapons, usually seen retracted on this rather rare machine, are extended. Also other fighters of the era are portrayed including the Bell X-1 that fills in for the Soviet parasite fighter that is actually the rocket plane that Chuck Yeager flew on the world's first supersonic flight. If you are an aviation enthusiast I highly recommend this movie. If you are fan of The Duke or are looking for action adventure or suspense entertainment, pass this one by, it's not for you.
