Lonelygirl15 Is Brainchild of 3 Filmmakers - Los Angeles Times
aspiring filmmakers who met at a mutual friend's birthday party in April: Miles Beckett, 28, a Web-obsessed medical school dropout; Mesh Flinders, 26, a screenwriter; and Greg Goodfried, a 27-year-old lawyer.
"Our goal was to tell a very realistic fictional story in this medium," Beckett said. He dreamed of using the various technologies of the Web, from comment boards to social networking sites, to both build a rich identity for a character and to let fans influence the story's direction.
Contrary to Internet speculation that the videos were all shot at once and rolled out in dribs and drabs, the team revealed that each installment was filmed only after the previous one had been posted.
The intent was to allow fan response posted in the comment section of lonelygirl15's YouTube and MySpace pages to determine the direction of each subsequent episode.
As an example of the fans' influence over the story line, what the team calls "collaborative storytelling," they pointed to an episode in which Daniel reveals his romantic feelings to Bree. "In the 'Hiking' video," Beckett said, "where Daniel filmed her, there were a ton of comments saying, 'Daniel likes you. It's obvious that the cameraman was completely in love with you.' We saw the comments and said this is the perfect opportunity to address this."
But as the mystery unfolded on computer screens, fans who became obsessed with the series took the investigation in a direction the filmmakers had not expected, searching for their identities and the true nature of the production. Having decided to remain anonymous, they found themselves unprepared.
As for the efforts to conceal the actress' identity, the team said they took precautions such as removing pictures of the actress from MySpace and the Internet. But throughout the furor, they said, she has been living openly in Los Angeles.
"There is no place better to hide then right in the middle of L.A.," Goodfried said. "Everyone is so focused on themselves that I guess they don't even notice."
As to where the story is going now that the veil of secrecy has been lifted, the team said the story of lonelygirl15 will continue, with the hope that the focus can now return to the on-screen mystery.
