Supergirl is a 1984 superhero film directed by Jeannot Szwarc, and stars Helen Slater in her first motion picture role in the title role of the DC Comics superheroine Supergirl. Faye Dunaway (who received top billing) played the primary villain, Selena. The film was a spin-off from the Salkinds' Superman film series which starred Christopher Reeve. The movie also featured Marc McClure reprising his role as Jimmy Olsen from the Superman films.
The film failed to impress critics and audiences. Slater, however, was nominated for a Saturn Award for her performance by the Academy of Science Fiction, Fantasy & Horror Films. The film does contain some expansions on the Superman movie mythology, such as taking the viewer into the Phantom Zone itself (in the first two Superman films, it was merely represented by a spinning square mirror). The story uses sorcery (a noted Superman weakness, but less commonly utilized than kryptonite) as a counterattack on Supergirl.
Released on video over the years by different companies, the film's first DVD release was by the independent home video company Anchor Bay Entertainment in 2000, under license from StudioCanal. Warner Bros. recently acquired the rights to the film and reissued it on DVD late in 2006 to coincide with the reissues on DVD of the other Superman films. Although it is related to the Superman films produced between 1978 and 1987 with Christopher Reeve, it is not included in any of Warner Bros.' Superman DVD box set collections released in 2006.
