Evangeline Lilly and Michael Emerson were there too, their identity having been kept a secret until the day they appeared, in a nod to the mysteries of the show.
This first clip is a little dark and shaky, but I love the excitement of the crowd, who were clapping and cheering and screaming as if they were at a rock concert combined with an Olympics final event.
In the beginning of this next clip, the crowd went wild again, counting down with the Dharma clock, and screaming when Evangeline Lilly came out.
The interviewers and Evangeline Lilly talked in French, and while I only know a few words of the language, the message was clear when Evangeline asked the crowd if they preferred Jack (boos) or Sawyer (big cheers).
Then Michael Emerson came out. More screams! Speaking in English, he had many interesting things to say about his character Benjamin Linus. At the end, some of the other stars, back in Hawaii, appeared in film clips to say hello to the Festival attendees. Josh Holloway got the biggest screams. Sawyer love is apparently the same all over the world.
How exciting this all looks! And how lucky the people who were there in the audience.
