Here's a little snippet from old articles.
Michael says "She is discussing it with TVB, now that the kids are older and she has more free time. I suggested that if the storyline and partners are good then go for it." (What about intimate scenes?) "I am very open minded, she didn't have any requests when I was filming those scenes with other actresses."
Anyway, seems to be a trend lately among veteran actors -- Idy Chan, Jamie Chik, Ray Lui....
Looking forward to it. ^^
