Ted Chiang, who wrote the story the film is based upon, approved the film, saying, "I think it's that rarest of the rare in that it's both a good movie and a good adaptation... And when you consider the track record of adaptations of written science fiction, that's almost literally a miracle."
The original name for the film was "Story of Your Life," the same as the source novella. Test audiences did not like that title, so it was changed to "Arrival."
"Dirty Sci-fi" is what director Denis Villeneuve and cinematographer Bradford Young called the look they created together for Arrival. Villeneuve wanted it to feel like "This was happening on a bad Tuesday morning, like when you were a kid on the school bus on a rainy day and you'd dream while looking out the window at the clouds."
Director Denis Villeneuve and the writing team took extensive efforts to ensure the movie's scientific ideology was accurate. Renowned scientist and tech innovator Stephen Wolfram and his son Christopher Wolfram were consulted to ensure all terminology, graphics and depictions were sound.
Amy Adams was Denis Villeneuve's first choice for Louise. She agreed to the role within 24 hours of receiving the script.
