Richard Donner had been approached about a possible Directors Cut of this film as early as 2001, however complex legal issues involving the cut footage as well as reluctance on the part of the director prevented any official restoration from taking place. All this changed with the production of Superman Returns (2006) which lead to Warner Bros. resolving all outstanding legal disputes regarding footage from the first two Superman films. By that time, public demand lead Warner Bros. to commission a "Donner Cut" edited by Michael Thau based on the original shooting script without Donner's participation. After repeated urging by Thau, Donner eventually agreed to approve of scenes as Thau progressed in editing. Over time, the more Donner allowed himself to participate in the project, the more the interest the director took in restoring his original concept for the film, even going so far as to bring screenwriter Tom Mankiewicz to the fold to insure story cohesion. The result is the closest film possible to Donner & Mankiewicz's original vision for the film.
