Some might find parallels with the Kennedy assassination as the actual perpetrators of the important historical event which climaxes this film are still disputed. There are many possible culprits and this film gives just one possible scenario. It does not go into politics but is a sombre psychological portrait, though with many touches of dry humour.
Excellent photography and recreation of Bogota in the 1940s. The acting styles are also redolent of that period. I am not sure if that was intentional, but it works well.
One slight puzzle. Although by the time of the events shown Roa is an obvious loser, there are many suggestions that he has (or at one time had) the ability to charm people. He has a beautiful and kindly young wife and other loyal and long-suffering friends. but only the weak, naïve, delusional and surly aspects of his character are ever shown (apart from his love for his daughter).
