Visible crew/equipment: When Sawyer finds his blue tarp that the boar ran off with earlier, Sawyer hears the whispers, then the boar reappears and chases him. When the mean old boar flips Sawyer over, the chain link fence (used for the stunt) is clearly visible beyond the grass, at the top right corner of the screen. (Also seen on Disc 7.) (00:12:10)
Visible crew/equipment: When Sawyer is tracking the boar, the camera is moving behind Sawyer, and you are able to see the camera's shadow move on the leaves. This happens in the shot before Sawyer gets on his knee checking out the boar tracks. (00:15:25)
Continuity mistake: When Sawyer shoots "Sawyer" there is a 15 ft tall grounded lamppost at the corner of the link fence, with an overhead curved head giving off the dramatic spot of light in the wet darkness, near the trash receptacle. However, earlier when Sawyer gets out of the car at the Sweet Shrimp, as he checks his gun, that towering lamppost is non-existent. (00:25:55 - 00:36:10)
Factual error: In the first scene in Sydney the camera pans from the opera house toward the rich North Shore suburb, except it shows that there are no houses on the shore whatsoever. In reality there are houses scattered across the shoreline.
Factual error: The location of the working dock in Sydney where Sawyer buys a gun doesn't really exist next to the Opera House, as pictured. The reality is the site has a glass cruise ship terminal, not a shabby wooden workshop.
Chosen answer: None of the main characters died in the plane crash. Many died on the island after the crash (Jack, Charlie, Sun, Jin, Daniel, Juliet, others), some lived on the island for an apparently long time after the crash (Hurley, Ben, Bernard, Rose) but some lived lives off the island after the crash (Sawyer, Kate, Claire, Miles, Aplert, and Lapidus). Remember that Christian tells Jack that "time has no meaning here," (in Purgatory). When everyone meets at the church, they are at the end of their lives however long that may have been and will now "move on" together. They look like they did on the island because that is the way they best remember each other.

That has to be the clearest explanation of the ending I've ever read.
