Just watched Overheard 2. Excellent HK crime thriller about insider trading. A lot people compare it with Overheard 1. But the obvious comparison is actually with early 1990s HK TV drama, The Greed of Man, which uses the same background context of the 1973 stock market crisis in HK and starring Lau Ching Wan and Kenneth Tsang pitting against each other. 20 years later, these 2 are still providing the acting chops that make this one of the best of 2011.
