Something has been left out...
When bad guys reached Van Gogh's painting, D.B. Woodside(bad guy), said that the code that was protecting Van Gogh's painting was changed. Then he mentions that a guy that was 'inside' did not tell him (them, the bad guys) anything about it.
From that moment on I was expecting to see this moment of 'reveal', where inside guy would show himself. I expected it to be either Hotels head security dude or the guy, who was captured together with protagonist's daughter, but the movie ended without revealing anything.
It makes me wonder whether someone forgot this detail of the story or it was cut out?
What do you peeps think?...
