Continuity mistake: When Frankie punches Barakov, pushing him through the window, not only do you see the wires lifting him, but it is obvious that the inside of the building is a studio set as not only does the window get broken, but also the wall above it is torn. The wall is obviously made of paper and the scenery outside the building is a painted backdrop. And when the angle changes to outside the building, only the window is broken but the wall is intact.
