'Lost' star Matthew Fox has warned fans that they may be left disappointed by the series finale.
Fox, who plays Jack Shepherd in the series, says he is concerned that fans have already "written it in their minds," which could cause them to feel let down by the final series.
Speaking to The Guardian newspaper, Fox said: "I really love the way [series five] ended because it felt like the board had been set, the pieces were in place.
"But when you have a show that makes people think as much as Lost; where you've made them hypothesise about what it all means and where it's all going on a plot level; ultimately you're going to disappoint them because they're going to want it to end a certain way, and it's going to end its own way."
The actor is the only cast member who knows how the final season of the hit drama (which starts on RTÉ2 on Thursday February 5 at 9pm) ends.
But when pushed for details he would only reveal that the last scene is "really beautiful and powerful".
He told the paper, "knowing stuff that the audience want to know... it's a quite a power trip, to be completely honest with you".
Fox added: "But the truth is that nobody really wants to know. If you're reading a really good book - I don't know too many people who want to turn to the final page and find out how it ends."
Some details of the final series are being kept secret, even from most of the cast, the actor explained.
Matthew said: "There are certain scenes that are never published in scripts.
"Every year, near the end, there are scenes that are omitted and the only people who ever know what's involved in that scene are the actors and a skeleton crew."
Lost will return to your screens for the sixth and final season on Thursday, February 4 on RTE2 at 9pm.
