I know the ending ended with 1 guy assuming the identity of the guy he thought he killed (or atleast hindered from traveling from the US to Switzerland) and he did so to take whatever was in his safety deposit box OR the money in his bank account. A SECOND GUY (the guy he thought he killed) disguised himself as the first guy because a second person was needed to withdraw the contents of the bank account. Pretty sure the second guy was the main character.
Probably a movie after 2001.
