Because the characters of Nikki and Paulo had to be convincingly incorporated into the plane crash scene featured in Pilot: Part 1 (2004), the editing crew meticulously watched hours of original footage to determine where additional scenes could be placed, which camera angles had not been used before, and which characters could be used for additional shots. The original beach set (still largely intact) was revisited and additional shots with Nikki, Paulo, and several original cast members were filmed. In some instances, acting was performed in front of a green-screen to incorporate the actors in existing (unused) footage. The resulting scene is a seamless cut of old, new and altered shots.
