It has been revealed that 'Lost' actor Matthew Fox is the only member of the cast who knows how the series ends.
In an interview with E! Online at the Monte Carlo Television Festival Fox said that 'Lost' would end in "an incredibly powerful, very sad and beautiful way".
"I think is going to be pretty awesome," said Fox.
He continued: "I think it is going to be very satisfying and cathartic and redemptive and beautiful. I've talked to Damon [Lindelof, executive producer] pretty extensively and every time I talk to him it's sort of surprising how moving it is just to talk about it."
Fox also talked about the beginning of the sixth series.
"It's very surprising and probably fairly confusing initially to the audience," he said.
"Like a third of the way in [to the season] I would guess we are going to [settle] in one time frame and it will be very linear - no more flashbacks, nothing. It will be on the island and sort of a final conflict to the end."
Fox added that all the storylines from earlier seasons would be resolved and that his character Jack and Locke (Terry O'Quinn) would "come head to head".
He refused to reveal any more details about their encounter.
When asked what would happen if he did, Fox replied: "Some guys would pull up outside this building in a white van and masks and I'd never be seen again."
