More on the 2012 movie

According to the Hollywood Reporter:

The film will reportedly center on an academic researcher who discovers that multiple versions of Earth co-exist in different dimensions, but all are threatened by an apocalypse to occur in 2012 prophesied by the ancient Mayans. By opening a portal into a parallel universe, he makes contact with his double to stop the prophecy from being fulfilled.

My guess is that the different dimensions will be exactly the same, but with different colored lenses used.
