Immediately after this shot, I think we see a shot of Vesper, removing a key sitting in the lock (if I am not mistaken). After the elevator submerges underwater in the sinking house in Venice and Bond dives in to try and rescue Vesper, he can be seen trying to unlock (?) or unhook (?) a latch to open up the steel elevator doors and free a trapped Vesper.
Those feelings aside though, I was confused about one scene in particular in Casino. It was quite a departure from the Brosnan films of reliance on CGI and over the top villians and schemes of world domination.
Much like you, I have already been out to see Casino Royale in theatres (twice on the first day in fact) and did enjoy many of the aspects of the film.
