After the success of Rugrats, os Anjinhos: O Filme (1998) and Rugrats em Paris: Os Anjinhos (2000), Nickelodeon came to an agreement with Ei Arnold! (1996) creator Craig Bartlett for an Arnold theatrical film, as well as a television movie. The original plan was for the theatrical film to be about Arnold searching for his parents, titled The Jungle Movie, while the television movie, originally titled "Arnold Saves the Neighborhood", was about Arnold saving his neighborhood from being torn down. Problems with the script kept the theatrical movie on hold for several years, and Nickelodeon, wanting an Arnold movie in theaters before the show lost its popularity, had "Arnold Saves the Neighborhood" converted into this film. However, a poor showing at the box-office, along with Craig Bartlett leaving Nickelodeon for Cartoon Network, caused The Jungle Movie to be put on the shelf indefinitely. However, the show's cult following convinced Nickelodeon to announce on November 23, 2015 that they have green-lit The Jungle Movie. Bartlett returned as a writer and executive producer, with many of the original cast reprising their respective roles. Ei Arnold! Na Selva: O Filme (2017) premiered as a 2-hour long T.V. movie on November 24, 2017, concluding the series.
Was originally scheduled to air on television as three half-hour episodes that would end the Ei Arnold! (1996) cartoon television series.
The first Nickelodeon animated movie to receive a PG rating.
