According to the credits, “The Fourth Protocol” (1987) is based on a novel by Frederick Forsyth. I never read the book, but the film is so weighed down with Cold War spy movie boilerplate, it’s amazing that Michael Caine didn’t get a hernia starring in it. It’s one of TV star Pierce Brosnan’s first major film roles (he plays a Soviet spy to Caine’s stock British spy). The worst part is that several Soviet characters are played by American actors who use their regular speaking voices. You can’t tell whether they’re actual Soviets, American double agents, or what. Very aggravating.
