Did you notice on the last featurette that it said “Choose to Believe – Part 1?” This featurette is the second part titled “Choose to Believe – Part 2.” This one features interviews with Stephenie Meyer, Diane Kruger, Max Irons, Jake Abel This one again has clips of Andrew Niccol directing the film. It also discusses the caves, and we get to see how it was constructed. There are a lot of new scenes in this featurette. I added some screencaps below and you can see Shawn Carter Peterson (Wes), Raeden Greer (Lily), and Scott Lawrence (Doc) sitting at the table with Saoirse Ronan, Chandler Canterbury, William Hurt, and Jake Abel.
I highly suggest you go to the original source, iTunes Trailers, and watch the video in HD. It is much better than YouTube HD.
