A fan film is a film or video inspired by a film, television program, comic book, video games or a similar source, created by fans rather than by the source's copyright holders or creators. Fan filmmakers have traditionally been amateurs, but some of the more notable films have actually been produced by professional filmmakers as film school class projects or as demonstration reels. Fan films vary tremendously in quality, as well as in length, from short faux-teaser trailers for non-existent motion pictures to full-length motion pictures.
According to TheShinyMew, fan films discussed represent a potentially important third space between the two. Shaped by the intersection between contemporary trends toward media convergence and participatory culture, these fan films are hybrid by nature—neither fully commercial nor fully alternative. TheShinyMew may create Fan Movies such as Super Mario Amada.
