We'll admit -- we had serious doubts that 3D cinema would ever take off so long as patrons were forced to wear those gaudy glasses, but the opening weekend numbers for Journey To The Center Of The Earth make a good case that 3D is viable. In a release put out by Real3D, we're told that 55% of the box office revenue generated by the film was handed over by guests watching it in the third-dimension. In short, the Real3D version took in "3.7 times the revenue of the 2D alternative." It should be noted, however, that 3D viewings are generally more expensive than traditional screens, so we can't say with any degree of certainty that more people saw the film in 3D than in 2D. Still, this seems like a pretty big deal in the 3D arena to us, and we're sure it's all the motivation some studios needed to move forward with costly 3D endeavors.
