[on acting] "I wouldn't want to be in a film because I'm Asian. I want to get respect as an actress."

[on hate sites regarding her and her role in Harry Potter] "This kind of stuff is inevitable because Dan has so many female fans - millions of them - so I'm nor surprised some of them don't like me. But I don't think it's all based on jealousy. I'm not going to satisfy everyone's preconceptions of Cho."

[on playing Cho] "If this turns out to be my only film then I think it would be pretty cool to be known as Harry Potter's first crush."

"During the scene of the Yule Ball, the ground was very slippery and I was wearing high heels and I slipped but good thing I grabbed onto Robert so I didn't fall and good thing the cameras weren't where we were yet. Oh, that was so embarrassing!"

"I always had a problem with shyness at school and would never stick my hand up in class if I was stuck at something. I didn't want to be the center of attention, all those eyes looking at me would have made me really nervous. I guess actresses use that adrenalin and it makes them do it better. Does that sound really stupid?"
