Yah im sure Sarah can act although i havent seen any Filipino fims for a long long time.
Ill give you a aqoute from another commentator here:
Why would casting have to be in Asia? There are a lot of Asians from the US.
Why indeed? there are more than 50 Million Asian-Americans here in the USA and basically there are also good singers and actress of Asian heritage that have not been given opportunity.
Charice is very talented coupled with all aces on her side, that's why she got known here in the USA.
Now to get Sarah who is already an established artist in the Philippines? That's a great injustice to Asian-Americans here.
Here chino why don't you read this article about how the Asian Americans see the current state of US entertainment.
http://www.nytimes.com/2007/03/04/world/americas/04iht-singer.4787848.html?_r=1&pagewanted=2 A lot of people supports charice who are non filipino cause she might be the breakthrough artist that will open up pop to Asian-Americans in the US.
And you are correct in your assumption lea and Monique have 10 years of play/acting/showbiz experience before they got discovered. Its also the reason why as a supporter of charice I dont include her on the list for kim cause her acting ability is untested.
