The greatest enemy of this movie has nothing to do with the film. It has to do with the fact that how many viewers will care enough about Italy and its communist 70's problems.
Dialogue is dialogue unless its written by Ed Wood. The twists in the plot are enough to keep you watching. And you may even be surprised.
Polical films require the viewer to accept some amazing coincidences, the kind of coincidences that occurred in "The Day of the Jacket," which is referred to in this film also.
The film didn't and wouldn't win an award, and who cares who the director is. The novel was thin also, but again, there is no international intrigue, just an American caught in a duplicious situation.
