I was reading today that this actor (well known for his role on the film: The Road) has a unique tradition that he takes everywhere he goes. He drinks "Mate". An Argentine infusion made of dried leaves of yerba mate. A metal straw is used for the drink.
He lived in Argentina since the age of 3 until he was 11 years old .
Viggo Mortensen (Hover)
I watched the video of an interview with Viggo and I couldn't believe the fact that he has NO accent when he speaks Spanish. He speaks just like a native and when I say that, I mean not even the tiniest trace. It is unbelievable! He sounds just like an Argentinian.
