In Interstellar, characters approach a black hole named Gargantua – shown as a sphere, surrounded by a glowing disc of gas and dust (known as an accretion disc). In an interview last year, Frankin told the Telegraph: "I realised that Kip [Thorne] had given us the tools to create this scientifically accurate image that didn’t need to be dressed up with the usual layer of science fiction nonsense. That was a special moment for me – when I realised we’d been able to do that."
