GSFOAT: Greatest Science Films Of All Time.

 

Seeing as I did the best Sci Fi novels quite a few months ago, I figured I should probably get around to doing the greatest sci-fi movies of all time.  As with the best sci-fi novels, for a film to be ranked as one of the best, it needs to be both accurate - and enjoyable. I'm not interested in films that are accurate but also boring. 

 

1.Interstellar.

 

Some would say that this film went on for far too long, seeing at it went on for almost 3 hours and had so many ploy conveniences and coincidences. The ending also divides viewers with many seeing it as brilliant but with others seeing as scientific fantasy. But Interstellar did so many things brilliantly - including hiring Hans Zimmer. Interstellar is one of the few films set in space that avoids aliens invading Earth and focuses more on philosophical themes, like the survival of humanity and its place in the universe. Interstellar also was incredibly accurate, with the film working with physicist Kip Thorne, a leading expect in astrophysics and professor at Caltech.  

The black hole Gargantua is one of the most realistic depictions of a black hole ever and the idea of time dilation seen in the film is actually accurate. General relativity means that near a massive object, such as a black hole, time for someone near the black hole will move slower than for somewhere further away.  It is entirely scientifically possible that someone stuck on a planet could age differently than someone nearby. 



Still, Interstellar does have its inaccuracies. There is no evidence that humans could access time like a 5D library and messages being sent via gravity is purely theoretical.  The main characters would probably not have survived near the black hole either. Wormholes, shortcuts through spacetime are also theoretically possible and are predicted by Einstein's equations. It is however important to note they have never been physically observed- although the portrayal of what a wormhole would look like is scientifically correct. 

The science aside, Interstellar's epic scale and emotional stakes make the plot almost addictive. This is a film that combines humanity's survival with the depth and complexity of fatherhood. 

 

2.Gattaca 

 

Gattaca is built around genetic engineering and eugenics, and it's so well done that even in the decades following its release and the subsequent developments in genetic research, it still feels like a warning and not a fiction. Arguably, Gattaca is becoming more relevant . 

Genetic engineering is something that is becoming more and more of a possibility. It may be a case that parents can one day pay to make sure their child has certain genes but doesn't have genes that are considered detrimental to the child's success. The main character Vincent Freeman does not undergo any genetic editing but his genetic profile indicates a high probability of several disorders and estimated lifespan of approximately 30 years ago. The audience is instantly to confront the ethics of genetic engineering - wouldn't most parents wish for a chance to extend the life of their child, reduce their risk of pain and suffering, and allow them to be the absolute best version of themselves?  

Gattaca does not rely on spectacle but psychological tension. Instead of focusing on the science behind the genetic engineering, the story focuses on the man with inferior genetics, fighting against a bias system. In Gattaca, a genetic registry classifies those created by genetic engineering as 'valid' whilst those conceived naturally are known as 'in-valids', Whilst genetic discrimination is illegal, genotype profiling allows valids to quality for professional employment while in-valids are relegated to menial work.  Whilst genetic discrimination is not something the audience would be familiar, discrimination for characteristics outside of a person's control certainly is. 



What also makes Gattaca so well done is that many of the so-called 'valids' are found to be suffering in various ways. One character Jerome, an Olympic swimmer, falls into a deep depression after placing silver; to him, he was designed to be the best and yet is somehow not. 

Gattaca also doesn't rely on fancy futuristic gadgets and environments full of CGI. The future seen in Gattaca appears to be a slightly altered version of the world we know today. This makes Gattaca seem much more believable and even more unsettling. 

All in all, Gattaca is one of the most thought provoking, but still relatable, sci-fi films that has been created. 

 

3.The Martian

 

The novel the film was based on is included on my list of best sci fi novels, and the film itself undoubtedly deserves to be recognised for the marvel that it is. Whilst aliens coming from Mars are a common theme in science fiction, the Martian manages to turn this around completely. The titular Martian isn't some space creature trying to destroy earth - it's Mark Watney stuck on an alien planet, technically becoming an 'alien' himself. Instead of trying to destroy or defeat a hostile lifeforce, the only antagonist is an environment that is just indifferent to whether Watney lives or dies. 

What truly makes the Martian a brilliant sci -film is how logical and grounded every step is, with real science being used to solve every problem.  The science seen is precisely that- real. The Martian is known for being one of the most accurate sci-fi stories ever made.  The botany used to grow potatoes, the chemistry used to make water and the engineering used to fix experiment is not just theoretically possible - it is practical. Plants have been grown in Mars-like simulants on Earth using methods shown by Mark Watney.  Creating water using hydrogen plus oxygen is basic chemistry. Even the rendezvous in orbit as unbelievable as it might seem is grounded in real orbital physics. Still, even the best sci-fi films aren't perfect.  The opening storm that kickstarts the entire plot is completely unrealistic. Mars' atmosphere is just too thin to produce that level of force. 



Despite its logical, grounded and controlled sensationalism the Martian is incredibly compelling. In my opinion, there are two reasons for this. One reason is how real and clear the stakes are - the running out of food or equipment failures.  A degree is not required to understand any of it which makes it so much more engaging. The character of Mark Watney is the second reason. Mark Watney, wonderfully played by Matt Damon, is humorous and resilient. But he also shows relatable moments of despair and doesn't develop into the cliched human superhero that so many sci films rely on. He's a normal guy, who downplays just how elite he must logically be. To be one of the first astronauts on Mars, Mark Watney, who describes himself as 'just' a botanist must be absolutely extraordinary and one of the most highly trained individuals on Earth. He comes across as casual and self-deprecating - and we the audience actually get to see where he goes wrong. We see his mistakes and his frustration. It's a degree of relatability that you rarely see in sci -fi films. 

 

4. Contagion.

 

It's a bit controversial to call this a science fiction film and probably even more controversial to rate it on my best sci films list but bear with me - there is method to my madness.

At its core, sci-fi is arguably about exploring science and its impact. Contagion does absolutely do that by looking at epidemiology and virus transmission. There's no futuristic tech or speculation - everything in this film is plausible - as seen in the COVID 19 pandemic. This film was initially released in 2011 but experienced a surge in popularity during said pandemic- for obvious reasons. 

The film is scarily accurate. There was no exaggeration in the exponential growth of the virus, and human contact chains. There was no miracle cure, just trial, error and time.  The film didn't just show the virus - it also showed social breakdown with misinformation spreading, panic buying and distrust. As we sadly learnt from the pandemic, this is incredibly accurate.  The film itself was inspired by real-life outbreaks such as the 2002-2004 SARS outbreak, and screenwriter Scott Z Burns worked with representatives of the World Health Organisation, and medical experts. 



Of course, accuracy isn't just the only factor in a good sci-fi film. The film tracks doctors, scientists, government officials and ordinary citizen, giving a plot that is global and interconnected. The film is presented with minimal melodrama, meaning that when major events occur, they seem more shocking - but even more real and unsettling. The film's explicit tracking of time really reinforces the realism of the fil, making it been more immersive and believable. The film even still manages to create mystery and suspense - by not revealing the source of the virus until the absolute end.  Instead of several films, where the audience knows more than the characters, the viewer is placed in a situation where they know just as much as the characters desperately trying to track down the virus and its victims. 

5.2001: A Space Odyssey.

 

This space epic was released in 1968 and is still widely considered one of the greatest sci fi films ever- and one of the greatest films ever made.  The film is recognised for its scientifically accurate depiction of spaceflight and its pioneering special effects. 

At the time it was amazingly forward-thinking, having consulted scientists and engineers.  The rotating space station and ship is based on centripetal force which is still a leading concept in real space habitat design today.  The satellite technology seen, with orbital satellites and space stations, was current technology.   Meanwhile, HAL 9000 was one of the earliest serious portrayals of AI and was inspired by real concerns about automation. 

There were inaccuracies and speculation. The timeline of human space presence was optimistic to say the least. But what the film did incredibly well was showing the realism and scale of space. It also got key ideas right - for example, AI becoming a major force, and the idea of long-term human space habitation.  Before this film, sci -fi films were full of monster movies and space adventures. 2001 Space Odyssey began a new era where sci-fi became serious cinema, with realistic science becoming central. 

What was also incredibly well done with 2001: A space Odyssey is how ambiguous the themes are. Unlike a vast number of sci-fi films, A Space Odyssey is incredibly philosophical. Conventional cinematic techniques are avoided - but a wide range of themes including human evolution, extra-terrestrial life and artificial intelligence are still explored. 




As well as this, the sound in the film is amazing. Dialogue is used sparingly, helping the audience actually appreciate the silence and vastness of space.  Long sequences are accompanied only by music; but instead of using original music, classical music is used. This results in sequences that are both visually and audially beautiful. 

It is fair to say that without 2001, the other films mentioned in this list would not have ever been made.
