exposure for the upcoming film release, DreamWorks and the licenser of the original play, The Tams-Witmark Music Library, announced that they would pay the licensing fees for all non-professional stage performances of Dreamgirls for the calendar year of 2006. DreamWorks hoped to encourage amateur productions of Dreamgirls, and familiarize a wider audience with the play. As a result, more than fifty high schools, colleges, community theaters, and other non-commercial theater entities staged productions of Dreamgirls in 2006, and DreamWorks spent up to $250,000 subsidizing the licensing. The Dreamgirls novelization was written by African-American novelist Denene Millner, and adapts the film's official script in chapter form, along with fourteen pages of photographs from the film. The book was released on October 31, 2006. A scrapbook, entitled Dreamgirls: The Movie Musical, was released on March 27, 2007. The limited edition program guide accompanying the Dreamgirls road show release was made available for retail purchase in February. In addition, the Tonnor Doll Company released "The Dreamettes" collection, featuring dolls of the characters Deena, Lorrell, and Effie, to coincide with the release of the film. Allusions to actual events Aside from the overall plot of the film and elements already present in the stage musical, many direct references to The Supremes, Motown, or R&B/soul history in general are included in the film. In one scene, Effie saunters into Curtis' office and discusses Rainbow Records' latest LP, The Great March to Freedom, a spoken word album featuring speeches by Martin Luther King Jr. This LP is an authentic Motown release, issued as Gordy 906 in June 1963. A later scene features Curtis and the Dreams recording in the studio, while a riot rages outside. By comparison, Motown's Hitsville U.S.A. studio remained open and active during Detroit's 12th Street Riot in July 1967. The photo shoot montage which accompanies "When I First Saw You", as well as the subplot of Deena being forced to star in Curtis' Cleopatra film against her will, reflect both scenes from and the production of Mahogany, a 1975 Motown film starring Diana Ross and directed by Motown CEO Berry Gordy. In a snapshot, Ed Sullivan appears presenting the real Supremes on his show. Among the more direct references are the uses of adapted Supremes album cover designs for albums recorded in the film by the Dreams. Three Supremes albums – Let the Sunshine In, Cream of the Crop, and Touch –
