Turning Japanese

There's a trailer up for Memoirs Of A Geisha here. I dunno about it. On the one hand, it stars Zhang Ziyi and Michelle Yeoh, who are always awesome. On the other hand, they're playing Japanese people (Zhang's Chinese, Yeoh Malayasian) and it's directed by the guy who did Chicago, which I haven't seen and don't really want to see. Hard to tell whether it'll be good or not from the trailer. Could go either way at this point.
