Please answer the following question: Information: - Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form. - Stunt casting is a term in casting that refers to hiring of well-known figures, such as movie stars or non-actor personalities prominent in some other field of endeavour, to play small roles on television series and in films. - An actor (or actress for females; see terminology) is a person who portrays a character in a performance. The actor performs "in the flesh" in the traditional medium of the theatre, or in modern mediums such as film, radio, and television. The analogous Greek term is, literally "one who answers". The actor's interpretation of their role pertains to the role played, whether based on a real person or fictional character. Interpretation occurs even when the actor is "playing themselves", as in some forms of experimental performance art, or, more commonly; to act, is to create, a character in performance. - Performance art is a performance presented to an audience within a fine art context, traditionally interdisciplinary. Performance may be either scripted or unscripted, random or carefully orchestrated; spontaneous or otherwise carefully planned with or without audience participation. The performance can be live or via media; the performer can be present or absent. It can be any situation that involves four basic elements: time, space, the performer's body, or presence in a medium, and a relationship between performer and audience. Performance art can happen anywhere, in any type of venue or setting and for any length of time. The actions of an individual or a group at a particular place and in a particular time constitute the work. - A performance, in the performing arts, generally comprises an event in which a performer or group of performers present one or more works of art to an audience. Usually the performers participate in rehearsals beforehand. Afterwards audience members often applaud. - A stunt performer, often referred to as a stuntman, stuntwoman, or daredevil, is someone who performs dangerous stunts, often as a career. - 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. - The Antoinette Perry Award for Excellence in Theatre, more commonly known as the Tony Award, recognizes achievement in live Broadway theatre. The awards are presented by the American Theatre Wing and The Broadway League at an annual ceremony in New York City. The awards are given for Broadway productions and performances, and an award is given for regional theatre. Several discretionary non-competitive awards are also given, including a Special Tony Award, the Tony Honors for Excellence in Theatre, and the Isabelle Stevenson Award. The awards are named after Antoinette "Tony" Perry, co-founder of the American Theatre Wing. - A stunt is an unusual and difficult physical feat or an act requiring a special skill, performed for artistic purposes usually on television, theatre, or cinema. Stunts are a feature of many action films. Before computer generated imagery special effects, these effects were limited to the use of models, false perspective and other in-camera effects, unless the creator could find someone willing to jump from car to car or hang from the edge of a skyscraper: the stunt performer or stunt double. - A stunt coordinator, usually an experienced stunt performer, is hired by a TV, film or theatre director or production company for stunt casting that is to arrange the casting (stunt players and stunt doubles) and performance of stunts for a film, television programme or a live audience. - Greg Powell ( born 13 May 1954 ) is British stuntman , stunt coordinator , actor and 2nd Unit Director nominated for an Emmy Award for his work on Band of Brothers . - A Grammy Award (originally called Gramophone Award), or Grammy, is an honor awarded by The Recording Academy to recognize outstanding achievement in the mainly English-language music industry. The annual presentation ceremony features performances by prominent artists, and the presentation of those awards that have a more popular interest. It shares recognition of the music industry as that of the other performance awards such as the Emmy Awards (television), the Tony Awards (stage performance), and the Academy Awards (motion pictures). - A production company or a production house provides the physical basis for works in the realms of the performing arts, new media art, film, television, radio, and video. - An Emmy Award, or simply Emmy, recognizes excellence in the television industry, and corresponds to the Academy Award (for film), the Tony Award (for theatre), and the Grammy Award (for music). - Television or TV is a telecommunication medium used for transmitting moving images in monochrome (black-and-white), or in color, and in two or three dimensions and sound. It can refer to a television set, a television program ("TV show"), or the medium of television transmission. Television is a mass medium, for entertainment, education, news, and advertising.
