- Science fiction film is a film genre that uses science fiction:
speculative, science-based depictions of phenomena that aren't
necessarily accepted by mainstream science. such as extra-terrestrial
life forms, alien worlds, esp, and time travel, often along with
futuristic elements such as spacecraft, robots, or other technologies.
Science fiction films have often been used to focus on political or
social issues, and to explore philosophical issues like the human
condition. In many cases, tropes derived from written science fiction
may be used by filmmakers ignorant of or at best indifferent to the
standards of scientific plausibility and plot logic to which written
science fiction is traditionally held.
