One of the hidden Easter eggs on the season 4 DVD is a short clip of Damon Lindelof talking about the power of the island. He says that the way the island is reaching out to find Jack could be likened to how Mr Fantasic might use his super-stretchy arms to reachout and grab a cup of coffee from another room.
I bought the Lost Season 4 DVDs a couple of days ago, and the first thing I did was start working my way through the bonus features. One of the features, titled “The Definitive Flash-forwards”, was something that I’d been tempted to have a go at myself. Basically its all the flash-forwards put together, in the correct order and presented as an episode of its own. It runs for almost an hour, it looks like they trimmed some of the flashes down a little, and it would definitely make the flash forwards make more sense for anyone who had trouble piecing it together themselves.
