How did Jarda, the last treadstone agent (besides Bourne) set off the silent alarm in his house? [While it's not explicitly spelled out, it's suggested that he was suspicious from the moment he entered the house (which is why he quickly goes for the gun in the fridge), so what he entered on the alarm keypad when he came in was not a disarm code, but was instead some sort of emergency code which called for backup.]

How do they know that Gretkov must be arrested? [Pamela Landy and her team both talked to the Russian Minister of the Interior and went to Moscow. Surely it didn't take the Russians long to figure out who Abbot and Conklin's associate was...assuming they didn't already know.]

In the final scene with Bourne and Landy, we find out Bourne's real name is David Webb. As this scene was only added after previews, were the audience originally going to find this out? [The original final scene, Jason walking through the snow, was described as "dismal". Something slightly more upbeat had to be added, paralleling the happy ending of "The Bourne Identity".]

Why is it so important that Landy's phone is engaged when Bourne asks the receptionist at her hotel to ring her? There must have been a reason why he specifically made sure that she is already on the phone before getting the receptionist to ring her, but why? I know that when the receptionist dials, Bourne looks over and finds out Landy's room number, but what was so important about it being engaged when he did this? [So that the operator couldn't tell Landy that someone is asking to speak to her, and alert her that someone is interested in her.]

Throughout the movie, Bourne is being hunted down because he killed the president of Russia, and Bourne says he's innocent, but at the end, he tells the president's daughter he killed them. Was the assassination ordered by Treadstone when it was operating? I really need an explanation of this, as it's really confusing me. [The president of Russia isn't involved in any way. Conklin and Abbot, Bourne's controllers, were involved in a criminal conspiracy which Neski, a Russian government official, was keeping a file on. Bourne was sent to kill Neski as his first, but off-the-record, assignment. When the "Neski file" was being sold to the CIA later, Abbot sabotoged the sale and framed Bourne for the killing with the help of a crooked Russian businessman.]

What was the name of the music piece during the final car chase, the one where Bourne smashed Karl Urban's car into the wall, killing him and is it on the soundtrack? [The final car-chase music is called 'Bim Bam Smash' and yes, it is on the soundtrack.]

After Marie dies, why does Bourne burn the pictures of her as well as her possessions but keeps of picture of him and her? [It would be standard practice from his old career as an assassin - leave no evidence behind, don't carry anything with you that you don't have to, so he burns all the passports that were created for her and so on. It's only when he gets the photograph of the two of them together that he can't bring himself to burn it - after all, he loved her; she means too much to him to just discard it completely.]

In The Bourne Identity, Conklin orders his staff to activate all Treadstone operatives. The only one in Germany is Pico, who is based in Hamburg. In the Bourne Supremacy, Jason Bourne returns to Berlin and kills the "last" Treadstone field agent. This operative never makes mention of the fact that he killed Conklin. Was he supposed to be the same field agent as Pico from Hamburg in Bourne Identity? If so, it is a different actor playing the same role. That may not be so uncommon, but there is a mistake in the city where the German operative is based - Jason Bourne tells him: "You should have moved" - as if he was always based in Berlin, not Hamburg. Anyone have an explanation? [Picot from The Bourne Identity is not in The Bourne Supremacy. The one Jason Bourne pays a visit is called Jardo (director Paul Greengrass mentions this on the commentary track) and lives in Munich (visible on screen), ie. South Germany.]

At the end of the film, Is Kiril trying to kill Bourne because it is his mission, or is he doing it simply out of bitterness that he failed the first time? [It is clear that Gretkov expects Kirill to finish the job he failed the first time around, since Gretkov contacts Kirill after he found out that Bourne was still alive. To quote the movie: Kirill: You told me I had one month off. Gretkov: You told me Jason Bourne was dead.]

When Jason Bourne is running from the Hotel Brecker, he runs under a bridge over a main highway. The bridge is on a diagonal and it looks like the bridge Lola ran under in 'Run, Lola, Run' which was also set in Russia. Was the same bridge used in both movies, and if not, what are the names of the two bridges? ["Run, Lola, Run" was not set in Russia, but in Berlin, and was shot there. Parts of "The Bourne Supremacy" were shot in Berlin, too. So chances are, it's simply the same bridge. I seem to remember seeing the same bridge in "Wings of Desire" (Der Himmel ueber Berlin). Perhaps it's just the most accessible for filming.]

Bourne did not kill the men at the deal in the beginning of the film, so who did? Matt Damon is definitely playing the killer, as we see his face for brief moments in between shadows, etc. in order for us to think it is him. Was it Kirill, Karl Urban's character? Or the former Treadstone agent? [It was Kiril, in the pay of the Russian businessman.]
