Titanic writer/director James Cameron is unveiling the first look into his highly anticipated sci-fi film Avatar, which doesn’t open until December 18, 2009. The worldwide trailer launch will be presented in all formats, including IMAX 3-D, IMAX 2-D, digital 3-D, digital 2-D, and 35mm 2-D. The extended, 16-minute look at AVATAR will unspool for two showings only on the evening of August 21. Canadian showings will be in select IMAX 3-D theaters in Toronto, Montreal and Calgary. Information on reserving tickets for these very limited showings will be available at avatarmovie.com. If you miss out on tickets, don’t worry, the trailer will also be shown in theaters and will be available online on Friday. In addition, this Friday, Fox will take the wraps off its special 3D/lenticular one-sheet posters for the film, Ubisoft will unveil the trailer for their videogame James Cameron’s Avatar: The Game, and Mattel will reveal the action figures for the film’s Avatar and alien Na’vi characters.
