There is a region 4 DVD of this film available in Australia from AV Channel.

Considering you can only get the MGM region 1 for no less than $44.12

I was wondering if anyone has seen the R4 version...? Perhaps it is better than the MGM.
Thanks.
P.S. I really hope someone will release Keep Cool (Zhang Yimou, 1997)
