I read Craig Thomas's cold war novel Firefox in the spring of 1982 and was unaware that a film adaptation was in production at the time. Having enjoyed the novel immensely, I was pleasantly surprised at the quality of the adaptation. The screenplay stayed true to the story and large passages of the book made it directly into the films screenplay. Then there was the sublime casting of Clint Eastwood as Mitchell Gant, the veteran pilot suffering with Post traumatic stress syndrome. Even the author Craig Thomas approved. The movie proved to be very entertaining at the time (I was fourteen), with its action sequences and special effects.
