Marvel and IMAX announced today that the Avengers: Infinity War Part 1 and Part 2 will be shot entirely with new IMAX cameras. This will be the first film to be shot entirely with IMAX cameras. Most other movies shoot a scene or two in IMAX, not the whole movie. The Infinity Wars will NOT be shot im 3D though, but will most likely be converted. The Russo brothers(directors of the upcoming Civil War and the Infinity Wars) had this to say:
The intent with the Infinity War films is to bring ten years of accumulative storytelling to an incredible climax. We felt that the best way to exploit the scale and scope required to close out the final chapter of these three phases, was to be the first films shot entirely on the IMAX/ARRI Digital camera.
