Factual error: There are multiple mistakes in the Italian passport for Clark. Febraio (February) is spelled with only one 'b', and the city Palermo is followed by the region name, which is not put on a passport.
Plot hole: When Carmine tells Clark about the job he wants him to do, he tells Clark to deliver a package for a "Larry London." Once at Larry's home, they are greeted by Edward, who lives with Larry. Clark and Steve introduce themselves and ask if he is Edward, to which Edward replies he is. Only problem is Edward is never mentioned by Carmine or anyone else, so how do Clark and Steve know about Edward? (00:20:00)
Continuity mistake: The Italian social club's outside facade looks nothing like the inside of the building. There are many more windows in the inside view for instance.
