Twentieth Century Fox will be opening Avatar on 3,124 3D screens in 2,032 theaters -- taking over virtually every 3D venue in the country -- plus 1,425 2D screens besides. In a few four- or six-screen theaters, the movie will be shown on every screen. Some analysts suggest that the movie could transform the movie industry, making 3D a standard and spurring the production of ultra-high-budget movies. (Estimates for Avatar's production and marketing expense range from $350 million to $500 million.) In an interview with today's (Friday) Washington Post, director James Cameron said, "Everybody at Fox is starting to relax a bit because people really are responding positively and the tracking is way up. ... I don't think this film is going to behave like Titanic, where it just defies gravity, but because of the 3D, we know historically 3D films tend to hold in and have legs." Cameron's Titanic was also released in December and had a modest opening. Nevertheless, it remained in theaters for 10 months and ranked No. 1 for 17 weeks.
