With all the excitement around the return of Matt Damon and Paul Greengrass to the Bourne franchise it's easy to forget that their last installment came out almost a decade ago. 

So it's probably best to kick back and re-watch the original trilogy again so that you can remember just what Bourne was doing with regards Treadstone and Blackbriar and just why Chris Cooper, Brian Cox, Albert Finney, Karl Urban and Clive Owen all wanted to kill him. 

However in this modern fast paced world it's hard to find the time to sit down and re-watch the previous 6+ hours of Bourne's adventures. Matt Damon understands this, which is why he put together this nice little recap which let's you know everything you need to know about the Bourne films in 90 seconds. 

Let his casual (and sometimes hilarious) narration refresh your memories.
