Inside, a new "social film experience" directed by DJ Caruso (I Am Number Four, Disturbia) invites Facebook, Twitter and YouTube users to participate in an in-production movie in real time. 
 
 A trailer for the project, funded by Intel and Toshiba, shows a young woman (played by The Day After Tomorrow's Emmy Rossum) waking up in a locked, padded room. There is no obvious way of escape and no link to the outside world other than a laptop to communicate with real people once filming starts on 25 July. 
 
 Users will be able talk to Rossum's character as the "blockbuster calibre" film is shot, and will be encouraged to help her think of ways in which she could escape. The trailer for the project is running with the tagline: "Her only way out will be to bring you in." 
 
 While this could potentially open up a new avenue in crowd-sourced film-making (labelled "social Hollywood" by Caruso in a promotional video) there is some suggestion that traditional Hollywood values will still hold some sway over the experiment. 
 
 "When the story begins everyone can play a part," said the director. "But with the Social Casting Call we're looking for one talented, well-connected person to make a special cameo in the final film." ||||| Your Facebook Posts Could End Up Inside Emmy Rossum's New Horror Movie 
 
 Unlike other productions, “Inside” will engage the audience and allow them to play a role in the film by interacting on social channels. A social casting call will result with one lucky participant cast to play a role via a YouTube video that will then be incorporated into one of the film’s episodes. Others can join in the project during the live social experience by posting on the main characters Facebook wall or tweeting which then has the chance of being incorporated into the next film episode.

 You know DJ Caruso best as the director of movies likeor big budget thrillers likeand. But in between traditional film projects, he’s trying something kind of different. His next movie is calledand you could be a character in it. They’re callinga “social film”.What does that mean? Here’s how they’ve explained it to us.That doesn’t mean the film doesn’t have some sort of plot, ready to go. Actually they just finished shooting it today, in Los Angeles, and we have the movie’s first teaser trailer. Check that out then I’ll see you afterward for more detail on how this all fits together.Alright, so there’s the trailer. What you saw there is the basic framework of the movie, an overall plot which I guess will hold all the social stuff together. That stars Emmy Rossum as Christina, “a 20-something girl who has been trapped in a room and left with a laptop and an untraceable Internet connection. Scared with no idea of what awaits her, she mobilizes her social network to help disseminate clues to figure out where she is being held and hopefully rescued. “You, the audience, will play the part of her social network. Starting on July 25th one piece of the film will be released every couple of days across different social media platforms. Users will respond to those pieces of the film with tweets, Facebook postings, and other methods. That input will be woven into the film itself to help the Emmy Rossum character unravel her mystery. Then on August 14th, the entire project, with YouTube videos, tweets, and all will be edited together into one single film and released in its entirety.Be a part of the film by following along on its official site TheInsideExperience.com ||||| Lonelygirl15 appears to be an innocent, home-schooled 16-year-old, pouring her heart out for her video camera in the privacy of her bedroom. But since May, her brief posts on the video-sharing site YouTube and the social networking hub MySpace have launched a Web mystery eagerly followed by her million-plus viewers: Who is this sheltered ingenue who calls herself "Bree," and is she in some sort of danger -- or, worse, the tool of some giant marketing machine? 
 
 No one has publicly come forward to lay claim to her work, but she is starting to look as connected in Hollywood as any starlet. Three lonelygirl15-obsessed amateur Web sleuths set up a sting using tracking software that appears to show that e-mails sent from a lonelygirl15 account came from inside the offices of the Beverly Hills-based talent agency Creative Artists Agency. 
 
 The apparent CAA link takes its place alongside other tantalizing pieces of evidence that lonelygirl15 is not who she claims to be: a copyright for the name obtained by an Encino lawyer, and a plot line that, leading speculation suggests, will turn out to be the lead-in to a horror movie's marketing campaign. 
 
 CAA spokesman Michael Mand said he "could neither confirm nor deny" that the agency is representing whoever is behind the 27 video posts. (Other talent agencies and production companies contacted by The Times denied any connection.) 
 
 As to horror film rumors, calls made to several studios found no such plans -- but plenty of fascination for the way in which a Hollywood-ready cultural phenomenon has been built from a grass-roots Web platform. Lonelygirl15, many say, is the next-generation "Blair Witch Project," using interactive forms of storytelling that, like the 1999 hit, tries to trick an audience into thinking it's true. 
 
 Indeed, if a commercial project does result, lonelygirl15 may prove to be a model of how to harness a groundswell created on seemingly populist, user-driven websites such as YouTube and MySpace. 
 
 To fans, meanwhile, it doesn't seem to matter whether lonelygirl15 turns out to be a private citizen or part of something bigger. 
 
 Riana Giammarco, a Rhode Island 20-year-old who curates a lonelygirl15 discussion board (one of several on the Web) says the mystery is the principal draw for her. 
 
 "I like the community aspect of the mystery -- getting together and trying to figure it out," Giammarco said in a phone interview. "Though I would still watch if there weren't a mystery, the videos wouldn't appeal to me as much." 
 
 Lonelygirl15 began quietly, posting in May two amateurish tributes to other videos on the Web's confessional arenas. For a moment she was just one of thousands who post videos on the site each day, typically young people speaking into cameras about their personal lives, a familiar trope from reality TV. 
 
 On June 16, lonelygirl15 made her first appearance in a video, titled "First Blog/Dorkiness Prevails." Dark-haired, big-eyed and pretty, she blinked nervously and hugged her knees as she described living in a small town "hours from a mall" with strict religious parents and a friend named Daniel, who she didn't like "in that way." 
 
 Over the next three months, two dozen more videos hit the Web, spaced out every few days. Bree dangled hints about her life, revealing that she had spent her youth in New Zealand, was treated for "lazy eye" and had an obsession with physicist Richard Feynman. Oblique references popped up to "my religion," which was never named but which forbade things such as attending Daniel's high school graduation party. 
 
 Fans soon started to notice jarring details. A music clip from an undiscovered L.A. band was mixed in to her well-edited montage sequences. Her room was movie-set neat. Above her bookshelf hung a photo of famed occultist Aleister Crowley. Thin already, Bree talked about an upcoming religious ceremony that she would participate in, even though it involved going on a diet. 
 
 On the message boards, discussions revolved around the single shoot theory: that the videos must have been filmed in one batch, because they gave little or no nod to the furor erupting around them. The landscape of two outdoor videos had botanical clues that suggested Southern California. 
 
 Since June, the videos have regularly made it to the top of YouTube's daily "Most Viewed" list, averaging about 200,000 views each, with several topping 600,000 -- viewership many cable TV executives would kill for. 
 
 In late August, fans discovered that the Web address for lonelygirl15.com had been purchased before the first video even appeared, with efforts made to shield the identity of the buyer. 
 
 In early September, Web forums erupted with the news that lonelygirl15 had been trademarked and the application filed by an Encino lawyer named Kenneth Goodfried. (He declined to comment for this article.) Within days, the MySpace profile of Goodfried's daughter was being combed for connections to the video. 
 
 Independent film director and blogger Brian Flemming, who is known for creating edgy film events, became wrapped into the story when viewers became convinced that Flemming had constructed the whole thing in order to promote an upcoming film. 
 
 Flemming said he received more than 300 e-mails from people accusing him of involvement. 
 
 "People have been confronting me with coincidences, and I don't know how to explain it," Flemming said, choosing his words carefully for fear of furthering the theories. "It's been pretty crazy and actually not particularly desired. It's like a big gift being handed to me that I don't want." 
 
 In the last week, the videos have developed seemingly ominous themes. In "Bree the Cookie Monster," Bree and Daniel, on her bedroom floor, sample cookies they say they have made. Judging a contest is a purple monkey puppet, who holds up scores for each cookie recipe. The first cookie was given a "10." The second a "12," the third "06." 
 
 Viewers immediately asked: Why 06 and not just 6? Soon, a posting told the virtual crowd that Aleister Crowley was born on October 12, 1875." Could it be that the ritual lonelygirl15 had been preparing for would take place on Crowley's birthday?
– Social media meets Hollywood thriller in online movie project Inside, billed as the first "social film." Star Emmy Rossum wakes up in a locked room with no way to communicate with the outside world except a laptop, which she uses to communicate with her social network—played by real users of Facebook, Twitter, and YouTube. The film's website invites users to audition via YouTube, reports the Guardian. After filming begins on July 25, producers say segments of the movie will be released every couple of days across different social media platforms, with users invited to respond and help create the next installment, CinemaBlend reports. After three weeks, the entire project, including user content, will be edited into a single movie.
