When Harry walks outside at night (1h32m) a gap in the background matte painting of the sky is visible behind the top of the tower, revealing it to be a studio set as the camera angle changes and the tower occludes the gap.
A Picasso painting, "Head of a Young Man" in black and white which is located behind Shabandar's desk is later seen hanging on the back wall of his art collection in an entirely different room.
When Nicole and Shahbandar fly by helicopter to see the city at dusk, the views are of Istanbul.
Nicole tries to impress Shahbandar with her knowledge of art by questioning whether his Picasso 'Blue Period' painting was from 1906 (as he states) or 1907. However, Picasso's 'Blue Period' was between 1901 and 1904, so both of them are incorrect.
