We think so alike.
Other than Oscar Chan, the other 2 actors that pop up in my mind is Fred Cheng and Sammul Chan.
*********************
If TVB really decides to adapt this famous novel, would you like:
I choose option 2 i.e. Wang Xi Feng rise and downfall, not becuase I particularly like the WAB, HOG backstabbing storyline, but because Wang Xi Feng is an interesting character. She was mostly vilified in the book, but it's undeniable that she's a strong woman and a complex character. So, I would like to see things from her POV. It's certainly more interesting than the Xue Bao Chai - Jia Bao Yu - Lin Dai Yu love triangle.
Who would be your pick of cast and what role they will play?
Wang Xi Feng = Ada Choi, Maggie Cheung
Jia Bao Yu = Fred Cheng, Sammul Chan, Oscar Chan
Lin Dai Yu = Tavia Yeung, Fiona Sit (after watching TOB, I'm not keen on Leila potraying a gentle and physically weak character. Tavia, on the other hand, aced her potrayal of the well brought up gentle girl in LOW)
Xue Bao Chai = Myolie Wu, Linda Chung
