Never did manage to watch that one but I think I can imagine. I reckon it'd be somewhere along the tone of voice he used for characters like Ekou in Karas and various characters in BL dramas where he played the mysterious dominant character. Dunno what he sounded like as Sasori since I've never watched Shippuuden. I love what he did for the Kusuriuri in Mononoke, though. Both character and voice are to die for, IMHO. One of his best works yet, which I think he sorely deserved to have gotten an award for.
