The script of the film was co-written by director Alfonso Cuarón and his son Hornas. It was co-written by Alfonso Cuarón’s old partner, "Harry Potter" series producer David Heman and Legendary Pictures Produced by Warner Bros., its theme and meaning are resistance to "impossibility". In the film, Caron needs to present the unimaginable scenes concretely, surpassing the audience's expectations of "this set of things we have all seen".
However, this was not the biggest challenge he faced. After more than 50 years, space travel has been somewhat eclipsed, partly because the movie makes us feel strange. It has been a long time since no director can evoke the awe that "2001: A Space Odyssey" brings to people, or the horror that "Alien" brings, or recapture people's inexplicable curiosity about outer space travel. There are very few characters in this "confined space" film in the field of space. There are almost only these two leading actors. Together, they will face the boundlessness of the universe and the loneliness of human beings-which also means that the heroes and heroines George Clooney and Sang Della Bullock's acting skills will face a big test.
Director Alfonso Cuarón said: "In order to make the audience as immersive as possible, I searched and communicated with a lot of astronauts, and obtained a lot of information. The heroine's one-man show is very difficult, so I pay more attention to details and pay attention to her every breathing rhythm. For special effects, the biggest challenge of the film is to express the weightless state and present it to the audience. In addition to letting the actors forget the feeling of gravity as much as possible, we also use a lot of CG Animation technology makes the synthesis more realistic."
