Most fantasy uses magic or other supernatural elements as a main plot element, theme, or setting. Magic and magical creatures are common in many of these imaginary worlds. Fantasy is generally distinguished from the genres of science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there is a great deal of overlap between the three, all of which are subgenres of speculative fiction.  - The Big Bird Cage is a 1972 American exploitation film of the "women in prison" subgenre. It serves as a non-sequel follow-up to the 1971 film "The Big Doll House". The film was written and directed by Jack Hill, and stars Pam Grier, Sid Haig, Anitra Ford, and Carol Speed.  - A cinematographer or director of photography (sometimes shortened to DP or DOP) is the chief over the camera crews working on a film, television production or other live action piece and is responsible for making artistic and technical decisions related to the image. The study and practice of this field is referred to as cinematography.

The 500-year-old republic which preceded it was severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title "Augustus", effectively marking the end of the Roman Republic.  - Joe D'Amato (birth name: Aristide Massaccesi; 15 December 1936 in Rome  23 January 1999 in Rome) was an Italian filmmaker who directed roughly 200 films, usually whilst also serving as producer and cinematographer, and sometimes providing script-writing duties as well. While D'Amato contributed to many different genres (such as spaghetti westerns, horror, war movies, swashbucklers, peplums, and fantasy), the majority of his films are exploitation-themed pornography, both soft and hardcore. He is generally considered the most prolific Italian filmmaker of all time.  - A gladiator ("swordsman", from , "sword") was an armed combatant who entertained audiences in the Roman Republic and Roman Empire in violent confrontations with other gladiators, wild animals, and condemned criminals.

Pornography may be presented in a variety of media, including books, magazines, postcards, photographs, sculpture, drawing, painting, animation, sound recording, writing, film, video, and video games. The term applies to the depiction of the act rather than the act itself, and so does not include live exhibitions like sex shows and striptease. The primary subjects of pornographic depictions are pornographic models, who pose for still photographs, and pornographic actors or porn stars, who perform in pornographic films. If dramatic skills are not involved, a performer in a porn film may also be called a model.  - An exploitation film is a film that attempts to succeed financially by exploiting current trends, niche genres, or lurid content.  - Women in prison film (or WiP) is a subgenre of exploitation film that began in the early 1900s and continues to the present day.  - A film, also called a movie, motion picture, theatrical film or photoplay, is a series of still images which, when shown on a screen, creates the illusion of moving images due to the phi phenomenon. This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession. The process of filmmaking is both an art and an industry. A film is created by photographing actual scenes with a motion picture camera; by photographing drawings or miniature models using traditional animation techniques; by means of CGI and computer animation; or by a combination of some or all of these techniques and other visual effects.  - Coffy is a 1973 American blaxploitation film written and directed by American filmmaker Jack Hill.
