Material Girls is a satirical teen comedy film starring Hilary Duff and Haylie Duff. It is based on a script written by John Quaintance and is directed by Martha Coolidge, and it also stars Anjelica Huston, Lukas Haas, and Brent Spiner. It is co-produced by Patriot Pictures and Madonna's film production company, Maverick Entertainment.

The plot centers around the Marchetta sisters, Tanzie (Hilary) and Ava (Haylie), a pair of rich, spoiled socialties who enjoy material things such as shopping and dating rather than caring about their late father's cosmetics company. When a scandal involving one of the company's products turns into an investigation, the girls find their assets frozen and must adjust to life without their fortune. They are tempted to listen to their advisors and sell the company to their biggest competitor (Huston) but decide to honor their father's memory by trying to turn it around themselves.

The film began production on April 18, 2005, in Los Angeles, California. For the film's soundtrack, Hilary Duff recorded two new songs, "Play With Fire", and a Timbaland-produced cover version of Madonna's song "Material Girl", which was the inspiration for the film's story. Performed as a duet with Haylie Duff, it was supposed to be released as a single, but Haylie Duff said via MTV.com that its release had been cancelled because there was no time to shoot a music video.

On March 31, 2006, the entertainment site AndPop.com reported that Lukas Haas had said he did not expect the film to be released. These statements were confirmed on April 5, in an article in The Ryersonian. Haas expressed his unhappiness with the film, and said they had been trying to sell the film for a long time with little success. On April 6, the website Box Office Mojo reported that MGM had picked up the rights to Material Girls and would be releasing it on August 25 (this was later changed to August 18). On May 2, the official website for Martha Coolidge reported that it would be released on around 2,000 screens.

Material Girls was released in 1,500 theaters in the U.S. and debuted at number nine on the weekend box office chart, grossing $4.62 million dollars in its first three days of release. As of the 21st of September 2006, it sits at number eleven on imdb's Bottom 100 ranked movies of all time. According to some DVD websites and Hilary Duff fan sites, Material Girls will be released on two-disc DVD in the U.S. on December 19, 2006. The DVD will include an alternate ending, interviews, featurettes and material related to Hilary Duff's music career and forthcoming album.
