The producers of Lost are determined to keep the series finale a surprise - they've planned a "missing scene" which will keep the stars of the show in suspense until the day of filming.
The cast is in the process of shooting the last episodes of the desert island drama, ahead of the final installment, which will air in May.
Cast member Daniel Dae Kim revealed last month that the show's climax is "incredibly powerful" - but new top secret scripts mean the actor doesn't know the true ending.
Henry Ian Cusick, who plays Desmond Hume on the show, says, "All the actors have the scripts that goes up to the tenth act of the finale. (But) no actor has the eleventh act, to my knowledge. So we don't know what's happening in the final act, which I think we're gonna film soon. I've heard that even with the final act, there's a missing scene!"
