Recieved this information from Michele, a DarkUFO reader, who informed me of some newspaper articles about Rodrigo Santoro. Below is some of what Michele said based on the translations.
Rodrigo Sntoro, the brazilian actor that will be in Lost season 3 said in an interview to a newspaper here in Brazil that his role in the series will be a survivor of flight 815. I'll try to translate what he said to you:Sources: "Folha de São Paulo" and "Zero Hora".
"- The essence of this work is mystery, and this to me is completely new. We're talking for a month and I still don't know what I'm gonna do. I just know I'll be one of the survivors of the original group, and not one of the others."
Here the newspaper explains that the others is the group which is already was in the island. Santoro also said: "They said to me that's how it works: the actors are literally lost in the story. It's a trust relationship."
I was looking for another interview of Rodrigo Santoro to brazilian's newspaper and found one wich he said he will not be one of the brazilian man in the listening station. He also said that he will speak English in the series, altough he might have a brazilian origin. By the way, I have the links to the newspapers which I was referring to on my last posts.
As I see you always give the source of the information you post, i thought you may want those. I may send it to you, if you want. The problem is that those articles are in portuguese.
