Houston starred in the 1995 film based on Terry McMillan's novel. McMillan's sequel, "Getting to Happy," was released in September 2010; film rights went to Fox within a week. Gabler tells Vulture that the film was "the biggest barrier-buster for color lines," and that audiences "practically tore the theater down; we couldn’t get them to leave. All these young women in their twenties and thirties wanted to stay and talk about what they’d just seen: Suburban [black] women drinking Chablis who weren’t living in the projects or stuck in gangs."
No actress is lined up to replace Houston in the sequel, but Gabler suggests that Oprah Winfrey, a huge supporter of the first film, is not an inconceivable replacement. Vulture has more, as well as details on a planned remake (with eery timing) of Houston's "The Bodyguard."
