Science fiction has existed as a film genre since as far back as 1902 with Georges Melies' A Trip to the Moon. Science fiction often contains fantastic elements like space or time travel, robots, and aliens though they are often presented in a way grounded in reality. That is to say that these fantastic elements are often explained in a way that uses what contemporary knowledge we have of science and where it is headed. Other times they are not really elaborated on at all and are based more on fantasy, like Star Wars. Despite all the technological wizardry and complex science presented in science fiction films, science fiction at its core is most frequently used to explore humanity. Two movies that are excellent examples of this are the classical Invasion of the Body Snatchers (1956) and the baroque Blade Runner: The Final Cut (
Now, getting down to the actual quality of the films. Invasion of the Body Snatchers was directed by Don Siegel at his very best. Siegel had a history of working in Hollywood, learning his craft before taking the reins and becoming a director himself. Siegel, at his best combined art and intelligence with expert craftsmanship on every level, and he may not have directed a better film than Body Snatchers. The film too excels on every level, with expert characterization and believability, pacing and rhythm. Being a horror movie it is at moments truly terrifying, which is amazing considered how long ago it was made. Horror films have a tendency to become cheesy with time and that has not happened here. Invasion of the Body Snatchers is a great work of science fiction, a great horror story, and above all a great film.
The visuals in Blade Runner are some of the most beautiful in film. Blade Runner was only director Ridley Scott's third film after a career as a director of TV commercials. Sadly that shows. While Blade Runner is in fact great and touches on some very interesting themes, it is not a great film. As beautiful as it is to look at, it gets monotonous because the film is really just close up after close up. The images never have a chance to breathe. Scott's previous career probably had a lot to do with this, as directing for TV is different than directing for the big screen, and directing a commercial is even more different than a film. Here, stylishness comes at the expense of everything else, and outside of the art direction and music the film is not even really that stylish. Aside from that, Don Siegel does so much more in relating the audience to the characters in 80 minutes than Scott does in 2 hours. It stands as a wonderful artistic achievement yet it lacks the cohesiveness of Invasion of the Body Snatchers that comes from being well crafted and takes something good and turns it into something great. But oh well. Both films are very interesting and are definitely worth seeing multiple times.
