The Mandarin is half British, half Mongolian. He's also an extremely athletic martial artist. So for the purposes of this thread, only half white, half asian/pacific islander actors with athletic builds are acceptable. The first options that pop into my head are Manu Benett and Jason Mamoa. Can you think of some more options?

Mamoa and Benett aren't related to Mongols. So how's that racially fitting? One is Maori, other is Hawaiian. And though Mandarin is racially mixed, he doesn't look racially mixed. He's always been portrayed with Asian features. And Mandarin wasn't born in Hawai or in New Zeland. He was born, according to some comics, in the South China.

It would be more appropriate to find a Chinese actor with Mongolian ancestry, which wouldn't be that hard, since plenty of Chinese are genetically related to Mongols.

Sean Connery

@silent_bomber: I would take Sean Connery over Guy Pearce as Mandarin any day. At least Connery has some charisma.

I've got it! Scarlett Johanson!

Jackie Chan

Idris Elba

That fat chick from ghostbusters

@nerevarine_11: which one? There is two of them.

Ben Kingsley.

1. Chow Yung Fat

2. Ian Anthony Dale

3. Jackie Chan (him as a villain would be interesting)

4. Robin Shou (Lui Kang from Mortal Kombat)

Lewis Tan

He's half Asian, half British, and has that martial artist look to him.
