The name of Daniel Craig's character ain't mentioned in the film at any point, Even IMDB only have the character listed as XXXX, Dunno why they didn't name him though!
In the film's commentary, Vaughn refers to Craig's character as 'X'.
Craig is the film's narrator and it ain't exactly in his best interests to tell us his name...
