Retroactive continuity in the context of "The Karate Kid (franchise)"

Superman Returns is a 2006 American superhero film directed by Bryan Singer, and written by Michael Dougherty and Dan Harris from a story by Singer, Dougherty and Harris, based on the DC Comics character Superman. It serves as an homage sequel to Superman (1978) and Superman II (1980), ignoring the events of Superman III (1983), Supergirl (1984), and Superman IV: The Quest for Peace (1987). The film stars Brandon Routh as Superman, Kate Bosworth as Lois Lane and Kevin Spacey as Lex Luthor, with James Marsden, Frank Langella, Eva Marie Saint and Parker Posey in supporting roles. In the film, Superman returns to Earth after five years and discovers that his love interest Lois Lane has moved on from him and that his archenemy Lex Luthor is planning to kill him and reshape North America.

After a series of unsuccessful projects to resurrect Superman following the critical and financial failure of The Quest for Peace, Warner Bros. Pictures hired Singer to direct Superman Returns in July 2004. The majority of principal photography took place at Fox Studios Australia, Sydney while the visual effects sequences were handled by a number of studios, including Sony Pictures Imageworks, Rhythm & Hues Studios (R&H), Framestore CFC, Rising Sun Pictures and The Orphanage; filming began in March 2005 and ended in November.

Stephanie Brown is a superheroine appearing in American comic books published by DC Comics, most commonly in association with the superhero Batman. The character first appeared in Detective Comics #647 (June 1992), and was created by Chuck Dixon and Tom Lyle.

The character originated as the amateur crime-fighter Spoiler, who had taken it upon herself to foil her criminal father Cluemaster's schemes. Establishing herself as a Gotham vigilante, she would have a short, unsuccessful stint as the fourth incarnation of Batman's partner and sidekick Robin in the early 2000s, replacing her longtime love interest Tim Drake. Her time as Robin is plagued with struggles and dissensions with Batman, who eventually fires her shortly before her death at the hands of Black Mask. She is later revealed to have survived and returns as Spoiler, resuming her romantic relationship with Drake. In 2009, Cassandra Cain, the latest Batgirl, entrusts the costume and monicker to Brown; although she is initially reluctant due to Brown's disastrous spell as Robin, former Batgirl Barbara Gordon later takes Brown as a pupil, and the character's run as Batgirl largely redeems her, including in Batman's eyes.

In the comic book fan community, the apparent death and subsequent return of a long-running character is often called a comic book death. A comic book death is generally not taken seriously by readers and is rarely permanent or meaningful other than for story or thematic purposes. The term is usually not applied to characters who have the ability to return from the dead as an established power or ability, such as Solomon Grundy or Ra's al Ghul.
