You'd think being the lead in one of the most popular movie franchises of all time would make you immune to gaffes like this but apparently not.

Mark Hamill was invited to Disney's London offices for the day but it seems that whoever was handing out the visitor passes that day hasn't a breeze as to who he is. 

Hamilton is close enough right? Maybe it was just a practical joke or perhaps the person is Broadway musical nut.

Either way, Hamill took it in good spirits. After all it's not the first time this has happened to him.
