STAR WARS TRENCH RUN
Star Wars is an American epic space opera franchise, centered on a film series created by George Lucas. It depicts the adventures of various characters "a long time ago in a galaxy far, far away". The franchise began in 1977 with the release of the film Star Wars (subtitled Episode IV: A New Hope in 1981), which became a worldwide pop culture phenomenon. It was followed by the similarly successful sequels The Empire Strikes Back (1980) and Return of the Jedi (1983); these three films constitute the original Star Wars trilogy (Episodes IV–VI). A prequel trilogy (Episodes I–III) was later released between 1999 and 2005, which received a more mixed reaction from critics and fans in comparison to the original trilogy. More recently, a sequel trilogy (Episodes VII–IX) began with the release of Star Wars: The Force Awakens (2015). All seven films were nominated for or won Academy Awards, and were commercial successes, with a combined box office revenue of $6.46 billion, making Star Wars the fourth highest-grossing film series. Additional theatrical films outside of the main saga include the animated Star Wars: The Clone Wars (2008) and a series of anthology films, which began with the release of Rogue One: A Star Wars Story (2016).
Chroma key compositing, or chroma keying, is a special effects / post-production technique for compositing (layering) two images or video streams together based on color hues (chroma range). The technique has been used heavily in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture and videogame industries. A color range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as color keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific color-related variants such as green screen, and blue screen – chroma keying can be done with backgrounds of any color that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from most human skin colors. No part of the subject being filmed or photographed may duplicate the color used as the backing.
