"Avatar Day" show clip of Cameron's 3D movie

16 minutes of James Cameron's much anticipated, high-tech follow-up to 1997's 'Titanic' was released earlier this week.

Twentieth Century Fox is showing preview footage of the 3D sci-fi adventure at cinemas around the globe on Friday. The audience will include lucky fans who scored free tickets online to what they're calling "Avatar Day."

A glimpse at the toys, video game, and 3D poster associated with the film will also be unveiled Friday.

The opportunity to give fans a glimpse of the movie was the brainchild of Cameron himself.

The extended preview will show on 102 screens in America and 342 internationally. According to Fox, a total of 58 countries are participating.

Tickets to the event sold out within 24 hours after being released.
