In this documentary we have no clear answer. What it is makes an argument that real life espionage is 100% cloak and dagger. A possible Egyptian hero and a turned Israeli spy looms large. There is quite the side stories to support both. In this convoluted reality is the story of "The Spy Who Fell to Earth". And the title is wholly descriptive as Marwan's death was due to a fall. Was it the Israelis? Was it the Egyptians? Was it suicide? It remains an open answer. In this climate this documentary allows there is ample reason for at least two of these scenarios. Even in retrospect the concrete answer alludes those who seek it. One journalist feels a heavy burden in the outcome. This is an arresting confluence of events. There is ample information here to support either of the two possibilities of murder with no clear cut answer. Frustrating? That is true, but the story is larger and that is what this documentary does achieve. The bottom line is that playing between two passionately waring factions is fought with peril. That peril resulted in Marwan's death is the only thing that is certain. What should not be forgotten is that this was only one life of thousands that has been lost over this struggle. A life and death that remains still today.
