"Sorry… it’s a fad. A fad concocted and controlled by the major studios. The question is “why”? Here’s the answer: the studios are promoting 3-D films right now in an effort to convince the theaters to convert to digital projection. Once all theatres go digital, there will be no need for the studios to create expensive 35mm prints, they’ll be no more costs for reels and cans; the cost of transporting 100 pound film canisters coast to coast, the cost of storing prints in film depots and later, the cost of destroying worn prints will be eliminated. The savings to the studios will be enormous. The theaters have resisted the move to digital because it costs tens of thousands of dollars to replace the 35mm projectors and install the new equipment. Theaters contend there’s nothing wrong with 35mm film; that audiences can’t tell the difference, so why bother to convert. Thus the studios are gung-ho for 3-D in an effort to provide something that digital can do more effectively than traditional film equipment."
