I still havent seen this movie yet but im excited for it! I understand this movie is in ReaL-D 3D. ReaL-D is a different style of film rather than the multi color filter films, usually in (blue and red, green and red, orange and violet, pink and green, etc..) RealD Cinema is a digital stereoscopic projection technology. It is the world’s most widely used technology for watching 3D movies in theatres. It does not require two projectors, unlike older film-based stereoscopic 3D projection technology. A high-resolution, digital cinema grade, video projector is used. The projectors use Texas Instruments’ Digital Light Processing device or Sony’s reflective liquid crystal display. RealD has an exclusive agreement with Sony to provide technology to project 3D movies with the Sony 4K projector. RealD 3D cinema technology uses circularly polarized light to produce stereoscopic images. Circular polarization is preferable to linear polarization because viewers are able to tilt their head and look about the theater naturally with no loss of 3D perception. Linear polarization, on the other hand, requires viewers to keep their head within a certain degree of tilt for effective 3D perception, otherwise they can see double or darkened images. This is the basis of how the RealD 3D films work
