Fox confirmed the news to the Daily Mirror and revealed that fellow cast members probe him for answers: "Yes, it’s true. They understand I can’t talk about it, but sometimes they’ll ask, just hoping I’ll blurt it out."
The 41-year-old, who plays crash survivor Jack Shephard in the hit show, also added that he has become a chess fanatic to pass the time he spends on the set. "I play chess against the computer a lot," said Fox. "When I’m shooting in Hawaii, there’s a coffee shop not far from me and I have friends there now, who I’ve made over the game of chess. I go there a couple of mornings a week and we’ll play chess. It’s the greatest game."
Lost, which is nearing the end of its fourth season, will end in 2010.
