The Bourne Identity First Person edition

In this fan edit the movie plays from Bourne's perspective. All the cuts to Treadstone are removed so we the audience, are only learning information as JB does. This is until he speaks to them using an assassin's (Clive Owen) phone. This way we are still learning information as he does. Then later, when JB is coming for them, we see things from Treadstone's POV, but we know what is coming. The movie plays much more as a mystery that slowly unfolds as opposed to the more straight forward "us and them" movie that we all know and love.

Just watched this and it works very well; by reducing most of Treadstone, the focus is even more on Bourne's continued perplexity over exactly who he is and his relationship with the woman, so in a way it becomes more of a love story. (Can be found on Reddit/fanedits)
