First it has tons of commercials for Desperate Housewives DVD, Lost, and other old shows coming out on DVD.
Then there are six items in the menu:
Lost: The Journey- The recap episode.
Flashbacks and Mythology- Producers, etc. explain the importance of the flashbacks. We get to learn more about the characters than the people on the island. Flashbakcs also show that the group was more lost in their past life than in present life.
Notice that there are no camera moves in flashback, just wide angle shots, compared to the island when the camera moves around. Producers also note that they keep blue and green out of wardrobe, etc. in flashback to contrast with the island. Prop selection, names, and crossing storylines are very intentional.
How much mythology in each episode? That's a hard question for the producers. One said the French woman and the mystery of Alex will be an integral part. Season one was background to learn about people. Season 2 flashbacks will continue to explore who they are. Also, there will be more exploration of the island.
The producers promised to dish out enough answers so that people will not get frustrated.
Lost on Location: The Moth- Talks about Charlie overcoming drugs while showing shots of the cast on location at the church, and scenes from the episodes
Lost on Location: White Rabbit- Shots of Jack in the jungle and on the beach with cameras around. There is some talk about the intricacies of the relationship with his father. Then they explain the dangling from the cliff scene and we meet Jack's stunt double. Terry O'Quinn says he learned how to throw knives while on the show.
Lost: The Complete First Season- A long commercial for the DVD
Lost: Season 2- A pretty unrevealing promo with the tag line "They not the survivors they thought they were."
