This book was adapted into a film in 1937. The similarities are well, exact. Coulg give insight into where Lost is headed.

Synopsis of the film from Wikipedia:
Fleeing unrest in China, a small group of airplane passengers is hijacked by the pilot. The plane eventually runs out of fuel and crashes deep in the Himalayas, killing the abductor. The group is rescued by Chang (H.B. Warner) and taken to Shangri-la, an idyllic valley sheltered from the cold. The contented inhabitants are led by the mysterious High Lama (Sam Jaffe).

Initially anxious to return to "civilization", most of the newcomers grow to love the place, including academic Alexander Lovett (Edward Everett Horton), swindler Henry Barnard (Thomas Mitchell), and terminally ill Gloria Stone (Isabel Jewell), who miraculously seems to be recovering. High-ranking British diplomat Robert Conway (Ronald Colman) is also enchanted, particularly when he meets Sondra (Jane Wyatt), who has grown up in Shangri-la. However, Conway's younger brother George (John Howard) and Maria (Margo), another beautiful woman they find there, are determined to leave.

Conway eventually learns that his arrival was no accident. He was brought there by the High Lama to take his place. The founder of Shangri-la claims to be hundreds of years old, preserved, like the other residents, by the magical properties of the paradise he has created, but is finally dying and needs someone wise and knowledgeable in the ways of the modern world to keep it safe.

George refuses to believe the Lama's fantastic story and is backed up by Maria. Torn between love and loyalty, Conway reluctantly gives in to his brother and they leave, taking Maria with them. After several days of gruelling travel, she becomes exhausted and falls face down in the snow. When they turn her over, they discover that she has died...of extreme old age. Her departure from Shangri-la had restored Maria to her true age. Horrified, George loses his sanity and jumps to his death.

Conway continues on and eventually meets up with a search party sent to find him, though the ordeal has caused him to lose his memory of Shangri-la. On the voyage back to England, he remembers everything; he tells his story and then jumps ship. The searchers track him back to the Himalayas, but are unable to follow him any further. In the final scene, Conway returns to Shangri-la, to the waiting Sondra

This leads me to believe that Jack is Jacob. He was brought there to replace Jacob. That would make sense considering Christian is in Jacob's cabin with Jacob(Jack), his son. Also, the eye in the cabin I believe is definitely Jack's. Let me know what you think

Interesting point. There are so many different literary sources that compare to Lost I don't think it makes much sense to draw more conclusions about what is going to happen in the show.

Buuuuut, since we're comparing the two... Do you think Jack is going to die in his quest to return to the island? It seems like Jack's character is more in line with George than Conway. John Locke would be my obvious choice for the Conway character, perhaps John is made to leave the island?

I think its interesting to think of more possibilities of where the show is going, and this story from the 30's does just that.

I kind of have two theories. First off, Jack is the center of the show. Everything else is a backdrop for his story. I believe that Jack's undeniable need to FIX things is what is eating away at him in the future. I believe he will get back to the island to fix his biggest problem of his life, but it will lead to his death. He will die rescuing those he left behind, the ultimate sacrifice, which suits Jack to a T.

The second theory is that Jack is Jacob, and everything I said above is wrong. I don't know how or what it means, but its just a theory

That wasn't Jack in the cabin with Christian...I've reviewed the screen caps.

I do believe that Jack and Kate come to be the two skeletons they found in the caves in Season 1. I think that whatever they do to correct things will lead them to their death there, but together at last. A romantic, but tragic end to the show...

I think they eye from the cabin is somebody new. Last week I posted about a Lost magazine ad that I saw (which no else has seen yet) that had an unidentified character standing with the other main characters. I think its someone new, but I tend to get really wild ideas and then convince myself that they are true...

I had that thought way back in season one but didn't put much stock in it. Now that i think more about it... Jack was the one who wanted to move to the caves in the first place why wouldn't he want to return there if he and Kate were together on the island?

Here's some trivia about who was in Jacob's cabin. It's part of a Kristin interview with Jorge Garcia:

I agree with the idea that Jack and Kate could be the 'adam and eve' of the island. This led me to think about a possible conclusion:

Let's agree that the 6 were forced to say everyone on the island is dead ("I'm sick of lying" to Kate). Jack is now obsessed with 'fixing' his mistake in leaving the survivors behind. Fixing in his previous life destroyed his life (his wife, his dad). Fixing this in the future will save his life and redeem him. However, this will be his ultimate sacrifice, and he will die on the island, in the caves with Kate.

Here's the mindf*ck that this show could end on (and it will end with a mindf*ck). In that final episode, there is a final flashback to events on the island that we have already seen (or maybe other small events that we haven't). And what will look like a flashback the entire episode will actually be a flashforward in which Jack discovers his own body in the caves.

This theory keeps with motifs... Duality, Jack's obsession with fixing things, and the lost time element. As for everything else like Jacob, smokey, and all the supernatural stuff that we love to speculate about, it's just the backdrop in which to tell Jack's ultimate redemption story, and isn't the focus.

Just a thought... on the theories page.

Just for a visual...

Imagine in real-time Jack lays down in the caves to die next to Kate, who he has already placed there after she dies doing something to help everyone...

The next scene is the 'flash-back-forward' of Jack discovering the body with Kate...

The end

Very Soprano-like and a great way to end a mysterious show such as Lost

i think this movie sounds interesting. i wonder if it's available on dvd

This would be cheesey. I give this about .05% chance of happening.
