Something recently occured to me. The plot of the 1967 movie Billion Dollar Brain (the less-successful followup to the more famous 1965 The Ipcress File and 1966 Funeral in Berlin, all starring Michael Caine as Harry Palmer), while I though the movie plot kind of stupid when I first saw it years ago, the plot is today actually completely plausible, and it is odd that no modern James Bond or Impossible Mission-style movie has done it.
