Lost: Jack's Nightmare
Basically, Jack is on the "Purgatory" version of Oceanic Flight 815 and has a moment when they hit turbulence where he remembers the crash. Sort of a waking dream sequence, like when your life flashes before your eyes only in his case it's a different life.
The music is the Main Theme and Nightmare sequence from Alfred Hitchcock's "Vertigo" - written by Bernard Hermann.
I've been working on my own Lost project, building on what Michael Maloney has done on his website: www.chronologicallylost.com. I began making this video with the intention of using it as a sort of prologue before we really get into the story. I do not plan on making the entire project available to everyone, as I do not want to get myself embroiled in copyright infringement.
This was done entirely on Windows Movie Maker.
