Director Christopher Nolan is known for his innovative and visually stunning filmmaking techniques. In the film "Interstellar," Nolan's aim was to create a realistic and immersive experience for the audience, and he achieved this without the use of green screen technology.
Green screen technology involves filming actors in front of a green screen and then adding computer-generated special effects to the background. This technique is widely used in filmmaking to create fictional worlds and landscapes that are not possible to capture in real life. However, Nolan wanted to avoid the use of this technology to create a more authentic experience for the audience.
Instead, Nolan and his team used practical effects and real locations to create the film's environments. For example, the dust storms on the planet in "Interstellar" were created using practical effects and miniatures, rather than computer-generated images. The wormhole and black hole were also created using practical effects, such as a mixture of CGI and real models.
Nolan also utilized practical lighting techniques, such as using natural light sources like the sun and moon, to create a more organic and realistic look. This approach helped to create a seamless and immersive experience for the audience, as the special effects blended seamlessly with the practical elements of the film.
Furthermore, Nolan and his team used specialized equipment, such as the IMAX camera, to capture the film's stunning visuals. The use of IMAX allowed for a larger frame size and a higher resolution, which helped to create a more immersive and detailed experience for the audience.
Overall, Christopher Nolan's decision to avoid green screen technology in "Interstellar" was a deliberate choice that helped to create a more authentic and immersive experience for the audience. By relying on practical effects, real locations, and specialized equipment, Nolan was able to create a visually stunning and memorable film that remains a benchmark for filmmaking today.
