The 3D visual

i think everyone know these two movies. its really classic. the main characteristic of these two movies is the 3D visual. A 3D or 3-D (three-dimensional) film or 3D film is a motion picture that enhances the illusion of depth perception. Derived from stereoscopic photography, a regular motion picture camera system is used to record the images as seen from two perspectives, and special projection hardware and/or eyewear are used to provide the illusion of depth when viewing the film. 3D films are not limited to feature film theatrical releases; television broadcasts and direct-to-video films have also incorporated similar methods, especially since 3D television and Blu-ray 3D. Why people use this skills into these movie, its makes people perceived how great is the movie it is and enjoy  the vivid scene,  its likely be personally on the scene.
