In the movie The Bourne Ultimatum , the character Bourne watches Landy from an overlooking building .
When Landy tells him that his real name is David Webb and gives him the birth date `` 4-15-71 '' , Bourne tells Landy to `` get some rest '' because she was tired , tipping off his presence in New York ( a scene replicated from the end of the previous film ) .
