Rodrigo Santoro is famous in Brazil. He is known as the "Brazilian Tom Cruise." I'm sure at one point in time that was considered a compliment. It has been reported that he is joining the cast of LOST. No news on who he will be playing or how big his role will be. Personally, I don't care if he is in flashbacks or one of the "others" as long as he takes his shirt off.
This doesn't make up for them killing off Ian Somerhalder, but at least it is a step in the right direction.
