Science fiction film - Wikipedia, the free encyclopedia

Science fiction film - Wikipedia, the free encyclopedia: "Science fiction film is a film genre that uses science fiction: speculative, science-based depictions of phenomena that are not necessarily accepted by mainstream science, such as extraterrestrial 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."
