Ren Ishii kills Matsumoto and tells him to   look at her face, she asks him to look at more facial features (nose, chin.   etc.) to be recognized, and then before pulling the knife out, there is a   close up shot of her moving the knife up his stomach and then finally   pulling it out. There are a couple of close up shots of Matsumotos face as   hes dying as well that were eliminated from the US print and then a pan up   shot of Matsumotos blood covered and disemboweled body.
