There are a number of differences between Bernardo Bertolucci's movie "The Spider Stratagem" and the story on which it is based, Jorge Louis Borges' "The Theme of The Traitor and The Hero;" however, overall Bertolucci does a pretty accurate portrayal of the essence, at least, of Borges' story. Besides changing the "setting" of the plot, there is also much more information relayed in the movie. This is very much due to that the story is simply a suggestive piece, while the movie had to fill in all of the blanks. In the movie, Bertolucci had to add characters, motivations, and many vast details that are left out of the story.To begin with, Borges is very vague in his ideas on the semantics of his story. He begins filling in the details somewhat with the story taking place in Ireland. But Borges himself says that this is simply, "(for narrative convenience)."

He has no interest in knowing about his father. It is only in concern of the health of this ex-mistress that he actually chooses to stay. (She has a propensity for fainti...
