Behind the imagery
Our DNEG crew, led by Overall VFX Supervisor Paul Franklin and DNEG VFX Supervisor Andy Lockley were tasked with the challenge of accurately depicting the film’s wormhole, its supermassive black hole (Gargantua), the Tesseract (a four dimensional space allowing time to be seen as a physical dimension), digital space vistas for projection on-set (no greenscreen was used in any of the space sequences), robots TARS and CASE and the population of alien worlds with giant waves and landscapes of frozen cloud and ice.
It was important that our work was scientifically accurate and Science Advisor and Executive Producer Professor Kip Thorne worked closely with our R&D Team led by Chief Scientist Oliver James along with CG Supervisor Eugénie von Tunzelmann to ensure our work was grounded in actual science. For Gargantua, a new relativistic renderer (Double Negative General Relativity – DnGR) was created which produced compelling imagery based directly on Professor Thorne’s own equations. The majority of Interstellar’s VFX shots were completed in 65mm IMAX at a resolution of 5616×4096 pixels.
