7. Always confirm the kill

In the beginning of The Bourne Supremacy, Jason Bourne realizes that an assassin named Kirill (Karl Urban) has tracked him down. He immediately decides to get out of dodge, but not before picking up the love of his life Marie and racing through town in an SUV.

In the books, Marie survives and remains Bourne’s emotional and psychological rock, but the second movie immediately kills her with a bullet through the head, putting in place the sequence of events that drive Supremacy and Ultimatum. Kirill races across a field on foot, sets up camp and, from several hundred yards away, fires a bullet through the head of the driver, unaware that Bourne had just made Marie swap with him so he could go on the offensive.

Of course, Kirill makes the tragic mistake of failing to identify the body. Stupid, stupid mistake.

6. The book bitch slap

Who knew that an elaborate action scene that has Jason Bourne leaping over rooftops in Tangiers, racing through alleyways on motorcycles and detonating car bombs would be defined by the use of the simplest of props: a book? Fully reinforcing the character’s ability to think on the fly and use everyday objects as weapons, Bourne proceeds to hold back another CIA assassin using a book like an older brother would hold a palm to his sibling to fend off a fist attack, and then bitch slap him with it. And then punch him in the face.

5.  "We’d be having this meeting face-to-face"

Though it’s a slight rip-off of the Pamela Landy rooftop scene in The Bourne Supremacy, Paul Greengrass delivers another clever, grin-inducing moment in The Bourne Ultimatum when Jason Bourne convinces Noah Vosen (David Strathairn) that he’s going to be waiting in a New York City park. When Vosen arrives, he gets a phone call from Bourne, who proceeds to ask the Black Briar head where he is.

"I’m sitting in my office," Vosen declares.

"I doubt that."

"Why would you do that?"

"If you were in your office right now we’d be having this conversation face-to-face."

Boom! Not only does Jason Bourne reaffirm his willingness to take on his adversaries directly, but he uses the conversation to break into Vosen’s personal safe and get incriminating files that could bring the entire Black Briar program to the ground. Strathairn’s brilliantly subtle reaction is priceless.

4. "Jesus Christ. That’s Jason Bourne."

Toward the beginning of The Bourne Ultimatum, an investigative journalist (Paddy Considine) gets in over his head when he stumbles across the CIA’s inner workings. Jason Bourne, curious about what he knows, asks him to meet at crowded Waterloo Station in London. Bourne immediately realizes that the reporter is being tailed and proceeds to pick apart the CIA surveillance team one by one.

When Noah Vosen (David Strathairn) realizes who is responsible, his simple words defy the "oh shit" thoughts that must have been racing through his head. The entire sequence is intricately done and undeniably thrilling.
