When a film is released with a final cut made by someone other than the director, sometimes producers will subsequently release a director's cut of the film, which is a version of the film as the director would have cut it or more closely follows her vision of the project. A promise of a release of a director's cut can sometimes entice a director to join a project or help smooth over creative differences. These versions of a film can act as an additional marketing tool for film distribution, and often the term "director's cut" is used only for marketing purposes and has nothing to so with what the director actually wanted. Director's cuts are usually released via digital distribution, such as on DVDs or through streaming services.
