[To Be Quite Honest]

Watching this show makes me think that the British are trying to take over the world through dialect placement.

Lorenzo Richelmy (Marco Polo) - is Italian.
Benedict Wong (Kublai Khan) is British.
Remy Hii Prince Jingim aka "Eye Brows" is Australian.
Tom Wu (Hundred Eyes) was born is Hong Kong but raised in Britain.
Mahesh Jadu (Ahmad) being brown you'd say he's from... England, but he's actually from Australia.
Uli Latukefu (Byamba) Australia.
Chin Han (Chancellor Jia Sidao) is from The Dark Night Rises and Hong Kong.
Amr Waked (Yusuf) is actually from the Middle East (Egypt)!

I'm a big fan of historic TV shows. I had no problem telling the characters apart except for the Chancollor's sister Mei Lin: when she went to the Mongol pleasure palace, I didn't recognize her right away. A side note about Mei Lin (Olivia Cheng), she's from Edmonton

Spoiler!

which is probably why she hit the post and failed her mission.

The series cost 90 million to produce... I don't know how Netflix and Weinstien can recoup that kind of cost along with it's other shows. It's a larger budget than Game of Thrones.
