"Time Travel" can be called the product of extreme expansion of human curiosity and imagination, because only when humans are dissatisfied or overly satisfied with the real society, humans will give full play to their imagination to find a way to help humans understand the past and the past. "Find out" in the future! The same goes for those who go to movie theaters to see sci-fi movies, and the characters in them.

In this "Back to the Future" filmed in 1985, the protagonist Martin is not satisfied with his current family situation. His father's cowardice, his brothers and sisters' ridicule, and his mother's unflattering attitude all made him want to escape from his native family. Perhaps based on this, he met "Frankenstein" Dr. Brown. This pair of friends, who have been together for many years, completed the experiment of human time travel by mistake. With the help of the "flow container" invented by Dr. , driving , a sports car that uses plutonium as fuel, will travel through the world when the speed reaches 88 miles.

As a science fiction movie, rigor is also essential. The first is the rigor of time. At the beginning of "Back to the Future", along with the sound of the second hand and the pendulum, various clocks hanging on the wall appear in the picture, all pointing to the same time (near 8 o'clock). Next, there were many time reminders. The most direct one was when the doctor called Martin. It seemed that he had a "premonition" that Martin would come to his laboratory. Then the alarm clock on the wall rang, and the doctor asked: What is the current time? It's not eight o'clock. In fact, it's not that the alarm clock is 25 minutes late, but it's probably from 25 minutes later. In other words, the Doctor traveled to the future.

Secondly, science fiction movies need the image of a scientist as a symbol of the rigor of science fiction movies. Scientists can have some weird behaviors, fancy clothes, imaginative inventions, etc. But it also needs to have scientific basis or the existence of elements that can support science. For example, the portrait of a scientist hanging in the doctor's home, and even the dog raised by the doctor are called Einstein . Including the source of inspiration when the doctor invented the flow container, it is exactly the same as the universal gravitation discovered by Newton ! Science is not completely step-by-step. The contingency and inevitability of science complement each other.

Finally, the rigor of character relationships and moral aspects. Many times, science and morality are full of ambiguity and struggle. Even movies cannot try to cross the wall built between the two. After traveling through time, Martin met his young mother, who fell in love with him at first sight, but he could only find ways to keep a distance from his mother and work hard to promote the relationship between his parents. When Martin wanted to tell him the news about the doctor's "killing", the doctor decisively refused! But in the end he escaped from death, which is in line with the doctor's bohemian character. Even in movies with the ability to travel back and forth, the protagonist cannot act recklessly and ignore the laws of scientific development and the moral bottom line. Biff, who has been bullying his father since then, changed his life trajectory due to Martin's time travel experience and became a servant of the Martin family. This is also a change within the scope of reasonable imagination.

The biggest difference between the "Back to the Future" series and other films of the same theme is that it has a unique style that combines avant-garde science fiction with witty comedy elements, and the essence of the film is a return to the past as a structural framework. It focuses on the modern life and emotions of ordinary Americans and elicits countless humane jokes. This kind of original attempt was unique before the 1980s.

Easter egg: The film was released on July 3, 1985, which is three and a half months earlier than the story of the film. In other words, when the film premiered, the audience was watching what happened in the future. A bit ironic.

Although the term "science fiction film" appeared around 1926, the prototype of science fiction films had already been produced as early as the birth of film, such as French director Georges Mérieux's "A Journey to the Moon" (1902), "A Journey into Space" (1904) and "Twenty Thousand Leagues Under the Sea" (1907). Science fiction movies are assumptions based on science (existing science and hypothetical science); in the real world, they are impossible or have not happened yet. The film itself also relies on scientific theory and development to continuously realize its function as a "movie". The general view of is that when scientific concepts, artistic imagination and film methods are combined, science fiction movies will also be produced. It usually involves four themes: religion and rebellion theme, Verne-style scientific hedonism theme, theme of power and order, and theme of sin and salvation.
