- In 1996, when the book upon which this movie is based was first published, it was titled "Push: A Novel." The film was likewise originally titled, "Push: Based on the Novel by Sapphire," but in February 2009, the movie title was changed to Precious: Based on the Novel Push by Sapphire (2009) to avoid confusion with the 2009 action film Push (2009). When the novel was republished in 2009, it was as a movie tie-in edition with cover art from the film, a common enough practice regarding books that have been turned into movies. What is unusual about the movie tie-in version of the book is that the book's title had also been changed to the movie's - which means that the book is now called "Precious: Based on the Novel 'Push' by Sapphire," even though it is the novel "Push" by Sapphire.
Helen Mirren was originally cast as Mrs. Weiss. - Shot in only five weeks.
Over 400 girls were interviewed from across the country for the part of Precious. Gabourey Sidibe was cast a mere six weeks before the start of shooting after being forced to the audition by friends. - Gabourey Sidibe read the novel Push years before when her mother, singer Alice Tan Ridley, was approached to play the role of Mary in an earlier production that never came to fruition.
- Over the course of the shoot the production lost an editor, a cinematographer, three continuity people, three locations managers, two producers, two assistant directors, two sound people, two video playback people, and two caterers.
- Mo'Nique played a character by the name of Precious in director Lee Daniels's previous film Shadowboxer (2005).
- The film was produced independently by Lee Daniels Entertainment, and the completed film was caught in a battle between potential distributors The Weinstein Company and Lionsgate after its initial success at the 2009 Sundance Film Festival. Oprah Winfrey's Harpo Productions and 'Tyler Perry''s 34th Street Films signed on to lend promotional assistance to the production, and Perry's existing relationship with Lionsgate helped land the film a release through that distributor.
- Before filming the scene in which Precious slaps Consuela for saying "F for Fat", Lee Daniels told 'Gabby Sidibe' to slap 'Angelic Zambrara' as hard as she could while purposely not telling the other girls beforehand. In the film, the reactions from the girls in that scene after she does so is actually improvised.
- Oprah Winfrey said that when she say the movie, it "split [her] open", and that she immediately called Tyler Perry who gave her Lee Daniels' number, so that she could call him and tell him she would do anything to promote the film. When she called him, he was onstage getting an award at the Sundance Film Festival. Oprah later stated that this film was why "we make movies", and that she thought people might not "enjoy", but would "appreciate this experience".
