1. Which actor is most successful in handling both singing and acting career?

Personally, i think Andy Lau is.

2. There's a lot of celebrity do the conversion from singing to acting or vice versa but who is the most successful?

Lisa Wong, she's a good singer in her early days and prove herself to be a good actress in her mature years.

RAYMOND LAM

got both singing and acting skills

Raymond Lam , he is an amazing actor but he can also sing!

Andy Lau fits both description. He made a fortune out of his entertainment career and so you could view it as being a tremendous success. And he's been a popular entertainer since I was a puny 7-yr old boy and has been going strong for the past 20 years. He won the Best male Actor award at one of the annual Chinese awards for movies, so that is a clear indication of how he grew from strength to strength in his acting career. To top it off, he's humble and hardworking.

i Think Andy Lau. He a very good singer, in many movies and tv series .

Stephen is great. He produced, directed and starred in his own movie Kung fu Hustle

Andy Lau...he's been at the top in both acting and singing careers, now he even has his own production company, what more can u ask from him?!?!

also the late Leslie Cheung and Anita Mui would give andy run for the money also.

My answer is also Andy Lau. Top in series, singing and movies.
Anita, Leslie

But Lisa ? No, she wasn't a good singer, Jenny Chen and Teresa Teng was more succesful than her and in that time. She was successful in series in the 70s
If you call Lisa is successful in series and singcareer, I think Adam Chen is more succesful.

I also think Andy Lau, Anita Mui, and Leslie are the most successful actor and actress as well as singing... For the recent actor, i've say Kevin cheng...

My list, not in any special order tho...
andy lau, julian cheung, ray lam, adam cheng, steven ma (Not really, but he is okay) i don't know about the actresses tho....

what about kelly? she's not really in any acting though.

Andy Lau and Anita Mui, hands down, no questions.

i would have to say Andy Lau is really talented...Raymond Lam is also talented as an actor and a singer...but he has yet to reach the success of Andy

Andy, still as strong as he was 20 years ago, and even hotter and richer .. hehe !

yeh I think Andy Lau aswell. I think he deserve it as he is very good person

Yea i think Andy Lau too. He still keep going at his age and achievement. Comparing to other former Heavenly King, he is the only one who really keep busying at

I agree with you people bout raymond alm because then he got the looks and can sing and ACt! thats like 110% guy or maybe more..

I would say Andy Lau too and Jackie Cheung back in the late 80's and early 90's

Liza Wang has won the award for the most successfull woman 2005

If you say most successful now based on popularity then it's definitely Andy Lau. Though I don't really like his singing, I do think his acting is good. So if you ask me the one I LIKE the most that multi-task is NOT Andy Lau. It would be Richie Jen I think. I think his singing/songs are good and his acting is really improving a lot. I like Raymond Lam a lot also, I think his acting has improved a lot, but his singing, I think is just okay.

I agree Raymond has great potential to develop into a multi talented artists. Don't know why Hk ppl don't like hiom as much as Ron etc.

michelle ye, she hosted the olympics, acts, miss chinese, smart, and her sining is not bad
