Actually, he's a Maori from New Zealand. I looked up the actors and like TWD, many of the leads are foreigners. The daughter is Australian and the junky son is a Brit.
Is it a coincidence that so many actors on that show are from the British Commonwealth. Hmmm...The cast looks very Benetton, which must be some kind of directive. ( I’m a motley American, too, so I notice these things when it looks like a like a formula.)
All not very good actors. I prefer the cast from the original recipe TWD.
