IF you were an Authentic Junky then you wouldn't pick a name like Khan for a Pakistani character. Pakistan is 66% Punjabi and the pakistanis you see in England, USA, Canada are all Punjabis. Pathans ( Khans) are 17% of Pakistan and very tall broad, light, and have colored eyes. Most of them are poor. You should ahve pick a name for your actor as something like Chaudary, Malik, Chohan, etc if you are really authentic.
