I don't know how I missed this film for 40 years, but I corrected that mistake.
Not a blockbuster, with the only outstanding features being the cinematography and special effects, it is nevertheless a taut cold war thriller.
The interplay between Rock Hudson, Ernest Borgnine. Patrick McGoohan, and to a lesser extent, Jim Brown made this a film where you are constantly focused on who is the good guy, and who is the bad.
Long at 148 minutes, it never lags. There is a very good reason why Alistair MacLean novels make good pictures,
