8mm is a 
motion picture film format wherein each frame of the film is eight 
millimeters[?] wide.  It exists in two versions: regular 8mm and Super 8, a slightly larger format that eventually became the prevalent version of the medium.  Many 
independent filmmakers[?] such as 
Derek Jarman have made extensive use of 8mm film with remarkable results.
8mm was originally a consumer format film, but has become more of a format for film students who wish to learn the basics of shooting film.
There is also an American film entitled 8mm[?] about a private detective verifying the existence of a snuff movie.
