To cover every possible screen and audio option out there, James Cameron produced over 100 different versions of Avatar for distribution to theaters.
In some cases, a single multiplex required different versions for different auditorium configurations. Creative decisions involving light levels also led to additional versions. 3D projection and glasses cut down the light the viewer sees, so “Avatar” also had separate color grades at different light levels, which are measured in foot lamberts. “If we had just sent out one version of the movie, it would have been very dark (in the larger theaters),” Barnett says. “We had a very big flow chart with all of the different steps, so we could send the right media to the right theater.”
