Science fiction (or sci-fi) is a film genre that uses speculative,
fictional science-based depictions of phenomena that are not fully
accepted by mainstream science, such as extraterrestrial lifeforms,
spacecraft, robots, cyborgs, interstellar travel 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.
