Chuck points out this obscure Star Wars reference:

You should check out the new Madonna music video. It's for the new James Bond movie 'Die Another Day'. In the video Madonna is fencing against herself with one dressed in black and the other madonna dressed in white. During the duel the Madonna in black kicks the Madonna in white out of a circular window exactly like the one that Luke falls out of in Empire.

She even falls in the same way as Luke. Pretty obscure reference but worthy checking out.
