How do you be a part of the cast of Harry Potter audition or be part of it when im an Asian and im on my own country?

There's no reason an Asian can't be in Harry Potter if you look up Halle Berry, You'll find she's an African American that has fulfilled several roles originally written for a white actress, such as the Flintstones which originally had no African members but her acting was so good they cast her.You'd have to keep your eyes pealed and find out if and when they were auditioning and jump on a plane!I wouldn't attempt to do this if you weren't 100% positive you could fulfill the role they were looking for.and even then it's not gaurenteed you'd get the part as there's a lot of compettition.Good luck X
