In preparation for watching Jason Bourne, I'm binge re-watching all the Bourne films since it's been many years since I've seen the earlier ones in particular.
Something just struck me in doing so. On the off chance it might be a spoiler to someone, I'm hiding it here:
Bourne Supremacy ends with the scene of Bourne observing Landy and telling her she "looks tired". Then this exact scene plays out roughly 75% through Bourne Ultimatum.
This seems to make it quite clear that the first 3/4 of Ultimatum, actually overlap with the events of Supremacy. But I'm having a hard time wrapping my head around how that's possible since in Ultimatum we see Bourne go through all kinds of stuff that we didn't see him go through in Supremacy.
So what gives with the overlap?
