Most people watch (view) movies as a type of entertainment or a way to have fun. Movies or films are a type of visual communication which uses moving pictures and sound to tell stories or teach people something. This means that copyrights granted by the law of a certain state do not extend beyond the territory of that specific jurisdiction. Copyrights can be granted by public law and are in that case considered 'territorial rights'. These rights frequently include reproduction control over derivative works distribution public performance and moral rights such as attribution. It is often shared among multiple authors each of whom holds a set of rights to use or license the work and who are commonly referred to as rights holders. Some jurisdictions require 'fixing' copyrighted works in a tangible form. A copyright is subject to limitations based on public interest considerations such as the fair use doctrine in the United States. Copyright is intended to protect the original expression of an idea in the form of a creative work but not the idea itself. The creative work may be in a literary artistic educational or musical form. Copyright is a type of intellectual property that gives its owner the exclusive right to make copies of a creative work usually for a limited time.
