Jason Bourne is a secret agent who has lost his memory, on the run with Marie, a young woman who helps him. Start in the Marais at the secret apartment of Treadstone, the programme that trained him, on Place du Marché-Sainte-Catherine: this is where the Paris story ends. Île Saint-Louis, where Bourne and Marie hide, is about 10 minutes south. From there, follow the Seine west for about 20 minutes to Pont Neuf and the Pont des Arts, where Bourne disappears into the crowd in the last Paris shot. Hôtel Regina, where Marie gets a man's phone records out of the front desk, is about 15 minutes further.
The rest of Paris needs the metro. In the 16th, the mansion of Wombosi, an exiled dictator, on Place des États-Unis, and Avenue Kléber, used for the car chase, are five minutes apart. Gare du Nord, the steps where Bourne drives a Mini down in Belleville and La Grande Arche are each in a different corner of the city: plan two days, one area per morning.
Wombosi's mansion is really the Maison Baccarat, with a shop and a restaurant inside, so you can go in rather than look from the street. Gare du Nord also appears in Lupin.
