International Sweethearts of Rhythm: America's Hottest All-Girl Band is a 1986 American independent short documentary film directed and produced by Greta Schiller and Andrea Weiss that presents a history of the International Sweethearts of Rhythm, the first racially integrated all-female jazz band in the United States.

Band members discuss the early touring years of the group, designed to raise awareness and funds for the Piney Woods School.

Scenes are included of women performing many different types of non-traditional jobs during World War II, and Winburn discusses her former role as director of a male jazz orchestra that was interrupted when many of her musicians were drafted into US military service.

A comparison is made between all-white jazz bands popular at the time and the sound of the predominantly black Sweethearts.

Archival footage includes the white singer Ina Ray Hutton and her all-female band, the Melodears.

Tiny Davis' role as the heart of the band is mentioned and contemporary footage of her performing excerpts from the song "Mack the Knife" is included.

The film discusses the demise of the group due to lack of jobs for female musicians after service men returned home, as well as many Sweethearts leaving the band to start families of their own.

[6] The filmmakers located their interview subjects thanks to the work of Marian McPartland who had organized a Sweethearts reunion for the 1980 Kansas City Women's Jazz Festival.

Band member Roz Cron provided information that allowed the directors to contact the former Sweethearts interviewed in the film.

In 1986, with much of the work on the film completed, Reitz parted company with Schiller and Weiss over creative differences and disagreements over copyright license issues.

The group of the title is an interracial, all-women swing band that enjoyed enough popularity during the 1940s to be remembered affectionately by the fans who are interviewed here.

The film offers toe-tapping selections by the 1940s band interspersed with lively reminiscences by the participants, who have aged gracefully in the intervening 40 years.

The Sweethearts documentary has also been shown at some colleges and universities,[20][21][22][23] frequently as part of classes or workshops on film, jazz history, or gender studies.

[45] In early 1991, the film was included in a segment called "Sisters in Jazz" which was part of a tour titled "Passion, Politics, and Popcorn" that represented selections from the 1989 and 1990 New York International Festival of Lesbian and Gay Films that played in 12 cities across the United States.

[46] In 1997, the film was screened at the Edinburgh Filmhouse in Scotland as part of a women in jazz double bill of director Schiller's works.

The National Endowment for the Humanities provided grants to more than fifty libraries or nonprofit organizations across the US to bring America's Music to their communities.

[7] An extra feature included on the DVD is a seven-minute interview with Schiller and Weiss recorded in 2006 upon the Sweethearts film's twentieth anniversary.
