Twin films are films with the same, or very similar, plot produced or released at the same time by two different film studios. Another possible explanation is if the films deal with topical issues, such as volcanic eruptions , reality television , terrorist attacks or significant anniversaries, resulting in multiple discovery of the concept. Screenwriter Terry Rossio notes that there are always film projects with similar subjects being developed in multiple studios while usually only one of them makes it into production in a given period of time, and therefore twin films are better regarded as exceptions to this tendency. While twin films usually are big budget films, a mockbuster can be made with a low budget, with similar titles, aesthetics or theme as blockbuster films. Producer Bingham Ray recalls a conversation where the screenwriter of the Truman Capote biopic Infamous phoned to announce that his script had been finished.
