Daniel Craig met actual assassins on-set of his first Bond outing, Casino Royale. How were they contacted? Who brought them to the filming? No-one seems to have an answer.
"You can see it in their (the spies') eyes," Craig told The Telegraph Magazine. "You know immediately, 'Oh, hello, he's a killer'. There's a look. These guys walk into a room and very subtly they check the perimeters for an exit. That's the sort of thing I wanted."
