Yes he does...
and the actor (Vas Blackwood I think his name) went to school in Alexandra Palace (very Cypriot area back then) and was bound to pic up some Greek being born and bred in that area. Infact, he could speak better Greek than the character who was named 'Nick the Greek' in that film. Blackwood was the same actor was also in a comdey show in the 80's called the Lenny Henry Show and was often called a Malaka by Mike, the owner of the BBC radio station (Brixton Broadcasting Corporation
)
By the way, I HATE Guy Ritchie films...they do not represent real London at all and try to make out we are all cockneys which we aint. Guy Ritchie is a 'mockney' (a fake cockney) and his films are all kinda the same.
Look at Lock Stock, he got a fat bloke and greased his hair back and that was good enough to make him Greek. He didnt look Greek AT ALL!
