I find this amusing:
Language Problems on 'Geisha' Set
Chicago director Rob Marshall is finding filming on his latest movie Memoirs of a Geisha complicated, because his cast all speak different languages. Sony Studios refused to cast non-Asian actresses in the big screen adaptation of Arthur Golden's best-selling book about the life of a Japanese geisha, and boasts Chinese Ziyi Zhang and Li Gong, Malaysian Michelle Yeoh and Japanese Cary-hiroyuki Tagawa and Ken Watanabe amongst its stars. An insider on the Japanese set tells American gossip site Pagesix.com, "They hired a 'Pan-Asian' cast. So now they have Chinese, Japanese, Korean and other Asian actors and they have had to hire a load of interpreters, especially since there are like 15 Chinese dialects. It is costing a lot of time to do anything." Producer Lucy Fisher and Doug Wick adds, "We have a Chinese and Japanese interpreter. The movie may or may not be a day over schedule, but we are brilliantly on time for an epic and on budget."
