Kane Caged

In the scene after Kane's second wife leaves him, we see him very dramatically and violently trashing their room.  He trips around like an animal who is in a cage much too small and is throwing a tamtrum.  This situation is emphasized by the director's use of low camera angles that make Kane into a menacing giant with a low ceiling above.  After he destroys everything in the room, the effect of a "caged beast" is added to by that fact that he is being view by an audience of the servants from the palace.  It's almost as if he is an attraction in a zoo or circus that is being gawked over.
