Front and center are Jack and Kate. In the original scripts, Kate was going to be the main focal character of the series. She did not have the criminal back story of the pilot. She was a little older, wiser, married (and may be widowed after the crash). Jack was supposed to be one of the first initial characters to be killed off (purely for dramatic purposes; to show how the island was a dangerous place). But viewers were quickly drawn to Jack, so the network made him the focal character of the series. In many respects, Kate remained the main female lead, but with a more secondary role.
Just behind Jack and Kate, literally having Jack's back is Charlie. Charlie's original character development was going to be Jack's right hand man - - - his loyal friend who would be in the center of most of the action (in some ways Kate morphs into this buddy role for Jack). Charlie's character went from possible loyal companion to lone-sick, drug addicted puppy.
Sawyer stood in the fourth lead role in the photograph. His character had the built-in elements for conflict: cockiness, rudeness, humor, criminal intent, and ballsy personality. He was a primary character who really did not affect the main plot lines. His decisions did not affect the final ending of the series. He was more representative of "leave me alone" survivor than a community builder.
Interestingly, the next group represents the "family element" of the show. ABC billed itself as the family network. Sun and Jin were the allegedly happy newly weds who we would learn were escaping from her demanding father. Whether the language barrier and stereotypical discrimination elements were initially cast for the Korean couple is unknown. But their story seemed to be more filler episodes than an overwhelming key to the solving of any of the island's mysteries.
Now, Walt and Michael could have been huge factors in the island story development. Walt was in fact touted early that he had "special powers." The danger and cruelty of the Others was established when they kidnapped children like Walt. The dynamic of a child reunited with a father he never knew was probably the most complete and compelling story foundation in the series. But that story arc got the short shaft based upon Walt's actor literally growing out his part. Then the writers began to use Michael as some all-knowing McGuyver on construction, boating, etc. to make him an unbelievable character. The families never made it to the end as a complete unit. Sun and Jin's back story was better than their island story. Walt and Michael's story just fell off the face of the Earth with the muddy main story supernatural elements taking over the plot.
The first of the background characters were Locke and Hurley. This makes sense in one regard: both were loners. Hurley was supposed to be a successful businessman and Locke a knock-about bachelor who never could get his act together. But once the show began to be filmed, Locke turned into a miracle survivor on his own quest for acceptance and recognition from his peers. Hurley turned into a meek soldier who lent himself for comic relief. Both men were originally not supposed to play big roles in the series. But the viewers were quickly drawn to the excellent acting skills and personality traits to become fan favorites.
Ironically, the next background pair actually wound up together in the end even though their characters were polar opposites. Shannon was the typical rich bitch, spoiled brat persona which would have had a hard time adjusting to the primitive island life. She had little skills (except French) to contribute to any plot. She was cast for eye candy. Sayid was supposed to be another diversity character, with the background that would cast an evil eye toward him. As someone who fought against the Americans in Iraq, he would naturally be considered by the other survivors as suspicious and untrustworthy. The camp needed his skills but the camp leaders could not deal with the politics of accepting an outsider as an equal. Sayid's role grew to be that "go-to" mission specialist in electronics, weapons, rescues, tracking, etc.
Off by himself, which really happened as the series went on, was Boone. Boone initially had a greater role in the series, but with an ensemble cast he was not paired with a dynamic focal character. In the pilot he was put into the role of potential go-getter leader, but was quickly shot down by Jack. Boone was left to gravitate towards Locke's stronger outback character as the Gilligan to the Skipper relationship. In many respects, Boone had the target of being a red shirt in the writer's room.
The last character in the photo was Claire. She was developed as a main character in the original treatments. As a pregnant young woman, her story was a simple tale of an unwanted pregnancy, bad decision making, and a horrible end crash landing on the island. One would have suspected that she could have died in child birth, got the island infection or had mad PPD to become an outcast in the group. But for Charlie's diminished role to Jack's leadership squad, Claire would have been quicklly written out of the series. Still, her motherhood role did not have any bearing in helping the main island themes pan out into interesting reveals. In fact, the Others intense interest in her, her baby, her birth, the infection shots, the kidnapping and her rescue had no impact on the Season 6 story elements.
What is interesting to note from this photograph is Bernard and Rose are missing from it. They were a "family" element more stable than any other pairing on the show. They were the "adults" in the room. In many respects, they were the base line for common sense on the show. But clearly, they were never intended to have any major role in the series.
