Season 6 (2010)

On May 7, 2007, ABC Entertainment President Stephen McPherson announced that Lost will end during the 2009–2010 season with a "highly anticipated and shocking finale."[65] "We felt that this was the only way to give Lost a proper creative conclusion," McPherson said.[65] Beginning with the 2007–2008 television season, the final 48 episodes would have been aired as three seasons with 16 episodes each, with Lost concluding in its sixth season. Due to the writers' strike, the fourth season featured 14 episodes, and Seasons 5 had 17 episodes. Season 6 was planned to have 17 episodes, too.[12] However, on June 29 it was announced that the final season will feature an additional hour, making the number of episodes 18.[66]

Executive producers Lindelof and Cuse stated that they "always envisioned Lost as a show with a beginning, middle, and end," and that by announcing when the show would end that viewers would "have the security of knowing that the story will play out as we've intended."[65] Lindelof and Cuse stated that securing the 2010 series-end date "was immensely liberating" and helped the series rediscover its focus.[67] Lindelof noted, "We're no longer stalling."[67] The producers also plan to wrap up long-standing mysteries, such as the nature of the smoke monster, the four-toed statue of Taweret, and the identity of the skeletons from the season one episode "House of the Rising Sun".[68] Matthew Fox stated in a recent interview that in the final season, the characters of Jack Shephard and John Locke "will come head to head." A third of the way through the final season, the two time lines will be "solidified into one" and "will be very linear - no more flashbacks, nothing." [69] He has also claimed to be the only cast member who knows the ending of the series.[70]

During Comic-Con 2009, numerous sixth season reports were made including the announcement of the return of Jeremy Davies, Elizabeth Mitchell, and Dominic Monaghan,[71] as well as the inclusion of Nestor Carbonell as a main character.[72] Other announcements include Carlton Cuse stating both the time travel and flash-forward seasons were over, and they're moving into something different for the sixth season.[71] Josh Holloway stated his character Sawyer would revert back to his old self after the loss of Juliet.[71](emphasis added)


LOST producers talk final season

It's sounds like Jack's plan worked.

Elizabeth Mitchell (Juliet Burke) and Jeremy Davies (Daniel Faraday) will be back on ABC's "Lost" next year, along with several other characters who haven't been seen since the first season, said producers at Comic-Con.

The revelation confirms reports that suggested a "Lost" reunion of sorts for the final season. In May’s finale, the castaways detonated a bomb on the mysterious island in hopes of resetting the last several years of their lives.

The items were among a scant few tidbits dropped during a well-produced hour in San Diego that featured several new mock "Lost"-verse ads and parody shorts, but no new video from the final season.

"There's a good chance you'll be seeing many characters you haven't seen since the first season again," said executive producer Damon Lindelof.
The final season, producers say, will in some ways resemble the first.

"(In the first season, the characters) were running around the jungle, things felt intense and surprising,” said executive producer Carlton Cuse. “We have a way that we're going to be able to do that in the final season too.”

Yet fans shouldn’t think that any sort of narrative reboot will invalidate everything that’s already happened, “because that would be a real big cheat,” said Jorge Garcia, who plays Hugo on the show.

“Just trust us,” reassured Cuse.

The show will also employ a new narrative device that’s unique to the final season.

"The time travel season is over, the flash forward season is over,” Lindelof said. “We're going to do something different."

Fans camped overnight to see the “Lost” panel, which occupied the fan convention’s largest ballroom that Comic-Con usually reserves for summer tentpole films.

LOST: THE FINAL SEASON @ COMIC-CON

By 9am, the line outside Hall H for the LOST: THE FINAL SEASON panel with co-creators Damon Lindelof and Carlton Cuse was already 1000+ fans deep, and the presentation wasn't until 11am. But the 6000+ fans that eventually made it inside were in for a real treat. Cuse and Lindelof came armed with tons of clips and almost equal amounts of special guests, and didn't disappoint even the hardcores that had been camping outside the San Diego Convention Center's Hall H since the night before.

After a montage of some of the creators' favorite LOST-related fan films, Cuse and Lindelof showed the audience a very well done promo for a fake throwback show that supposedly aired in the 80s, and which covered the mysterious Dharma Initiative that is such a huge part of the LOST mythology:

ABC debuts Lost online filler

Disney's ABC is launching a faux online documentary series about the history of The Dharma Initiative, the fictional research project at the heart of hit series Lost.

Mysteries of the Universe: The Dharma Initiative is a five-part short-form series that debuts on ABC.com on August 4 in the build up to the sixth and final season of Lost later this year.

The online 'documentary' is set in the early 1980s and attempts to "uncover the truth about the shadowy organisation" through interviews, research and eyewitness accounts. Kia Motors America is on board as sponsor.
