We're all well aware of the subtle and subjective art of the cinematic rating system. Remove a word here, take out an innuendo or slip of the nip there, and suddenly that risque adult fare becomes palatable for familial audiences. But here's a new goodie to consider: With the rise of 3D, will we start seeing the same film receive different ratings between the second and third dimension, and what will that mean for the ever-important box office take?

It seems that overseas in Sweden, the country's Board of Film Censors doled out two different ratings for Cats and Dogs: The Revenge of Kitty Galore. The 2D version was rated G, meaning everyone could see it without adult supervision, while the 3D version was rated PG, requiring adults to accompany tykes under the age of 7.
