They probably took the key elements of the true story, like the spooky setting and the main events, and added their own cinematic twists.
The filmmakers might have first researched the true story thoroughly. They could have interviewed people related to the events if possible. Then, they selected the most interesting and eerie parts to build the plot. For instance, if the true story was about a haunted school, they would focus on the classrooms, corridors, and the strange things that were reported to happen there. They also added their own interpretations in terms of the characters' motives and relationships to make the story more engaging for the audience.
They probably focused on the most shocking elements of the true story. For example, if there was a core event in the real story about a child's deceptive behavior, they exaggerated it for cinematic effect in the movie.
They probably picked out the most dramatic parts of the true story. For example, if there were certain strange behaviors in the real events, they made them more extreme in the movie.
The filmmakers likely took the core elements of the real story, such as the idea of a child with a hidden, disturbing nature, and built a fictional narrative around it. They might have exaggerated some aspects for dramatic effect. For example, Esther's actions in the movie are very extreme.
They might have used real - life testimonials from survivors. By including the actual words and experiences of those who were tortured, it gives a sense of authenticity. For example, if a survivor described the setting, the methods of torture, and their emotional state during the ordeal, the filmmakers could recreate these elements accurately in the movie.
Filmmakers often start by doing in - depth research. They study historical records, interview people related to the story if possible. Then they condense the key elements of the real story to fit the movie format. For example, in 'Hidden Figures', they focused on the main events and achievements of the female African - American mathematicians at NASA.
They likely took the key elements of the true story, such as the reported paranormal occurrences, and dramatized them for the screen.
They probably took the key elements of the true story, like the water problems and the spooky feelings, and exaggerated them for the movie.
First, they start with in - depth research. This includes looking at primary and secondary sources. They might also visit the locations where the events took place to get a feel for the setting. Then, they often work with consultants who are experts in the relevant fields. For instance, if it's a medical story, they'll have a medical consultant. Another important aspect is that they try to stay true to the essence of the story, even if they have to make some minor changes for the sake of the movie's flow.
They often work with a team of special effects artists. These artists use a combination of computer - generated imagery (CGI) and practical effects. For instance, in a movie based on a true story about a sea adventure, they might use a real - life model of the ship and then add CGI elements like stormy seas and sea monsters (if it was part of the legend associated with the story). This way, the clipped fx blend well with the real - life elements of the story.
They do a lot of research. They study police reports, interview witnesses if possible, and read historical accounts. For example, for a crime - spree - based movie, they'd look into how the criminals operated, what their motives were.
