SPOILER ALERT!!! SPOILER ALERT!!!

Lost star Matthew Fox dishes the dirt on the upcoming four season of this hit ABC show in the new issue of Entertainment Weekly (on newsstands Monday).

On the 8th episode of Lost this season: "There's going to be some huge mind-blowing (stuff). Jack gets people off that island, [and] suddenly he and the other people are very well known- it becomes this massive story because everybody thought that every person on this plane was lost…. Who are they? What is everybody else doing? Jack's mission was to get all of them off. It's the overriding force behind him. So, the fact that he ends up getting off and doesn't get that accomplished-I'm very curious to find out how that all goes down…. If I start giving you words about what I think it's really about, I'm going to be honing in on some stuff that I'm not sure I'm authorized to talk about. A truck might pull up and a bunch of dudes in suits get out and mow us down with Uzis."

On this season dealing with time travel and other supernatural elements: Really fascinating stuff. Last year, we find out Jack and Kate are off the island. How the f- did that happen? And why does he want to go back? In answering those questions, you have to start addressing the bigger, epic scope of the show. In doing that, you're going to get into questions about the show that the audience is just dying to start finding out. What is this island? Where is this island? When is this island?
