Problem: Background: Dreamgirls is a 2006 American romantic musical drama film written and directed by Bill Condon and jointly produced and released by DreamWorks Pictures and Paramount Pictures. Adapted from the 1981 Broadway musical of the same name by composer Henry Krieger and lyricist/librettist Tom Eyen, Dreamgirls is a film a clef, a work of fiction taking strong inspiration from the history of the Motown record label and one of its acts, The Supremes. The story follows the history and evolution of American R&B music during the 1960s and 1970s through the eyes of a Detroit, Michigan girl group known as the Dreams and their manipulative record executive. The film adaptation of Dreamgirls stars Jamie Foxx, Beyonce, Eddie Murphy, and Jennifer Hudson, and also features Danny Glover, Anika Noni Rose and Keith Robinson.
Context: Dreamgirls premiered on December 4, 2006 at the Ziegfeld Theatre in New York City, where it received a standing ovation. The film's Los Angeles premiere was held on December 11 at the Wilshire Theater in Beverly Hills.  Similar to the releases of older Hollywood musicals such as The Sound of Music, My Fair Lady, and West Side Story, Dreamgirls debuted with three special ten-day roadshow engagements beginning on December 15, 2006 at the Ziegfeld Theatre in New York City, the Cinerama Dome in Los Angeles, and the AMC Metreon 15 in San Francisco. Tickets for the reserved seats were $25 each; the premium price included a forty-eight page full-color program and a limited-print lithograph. This release made Dreamgirls the first American feature film to have a roadshow release since Man of La Mancha in 1972. Dreamgirls earned a total of $851,664 from the roadshow engagements, playing to sold-out houses on the weekends. The film's national release, at regular prices, began on December 25. Outside of the U.S., Dreamgirls opened in Australia on January 18, and in the United Kingdom on February 2. Releases in other countries began on various dates between January and early March. Dreamgirls eventually grossed $103 million in North America, and almost $155 million worldwide.  DreamWorks Home Entertainment released Dreamgirls to home video on May 1, 2007 in DVD, HD DVD, and Blu-ray formats. The DVD version was issued in two editions: a one-disc standard version and a two-disc "Showstopper Edition". The two-disc version also included a feature-length production documentary, production featurettes, screen tests, animatics, and other previsualization materials and artwork. Both DVD versions featured alternate and extended versions of the musical numbers from the film as extras, including the "Effie, Sing My Song" scene deleted during previews. Both the Blu-ray and HD DVD versions were issued in two-disc formats. Dreamgirls was the first DreamWorks film to be issued in a high definition home entertainment format. As of 2017, total domestic video sales to date are at $95.1 million.  A "Director's Extended Edition" of Dreamgirls was released on Blu-Ray and Digital HD on October 10, 2017 by Paramount Home Media Distribution. This version, based on edits done for preview screenings before the film's release, runs ten minutes longer than the theatrical version and features longer musical numbers (including songs and verses cut during previews) and additional scenes.

Problem: Background: Octavia Estelle Butler was born on June 22, 1947, in Pasadena, California, the only child of Octavia Margaret Guy, a housemaid, and Laurice James Butler, a shoeshine man. Butler's father died when she was seven, so Octavia was raised by her mother and maternal grandmother in what she would later recall as a strict Baptist environment. Growing up in the racially integrated community of Pasadena allowed Butler to experience cultural and ethnic diversity in the midst of racial segregation. She accompanied her mother to her cleaning work, where the two entered white people's houses through back doors, as workers.
Context: Butler followed Clay's Ark with the critically acclaimed short story "Bloodchild" (1984). Set on an alien planet, it depicts the complex relationship between human refugees and the insect-like aliens who keep them in a preserve to protect them, but also to use them as hosts for breeding their young. Sometimes called Butler's "pregnant man story," "Bloodchild" won the Nebula, Hugo, and Locus Awards, and the Science Fiction Chronicle Reader Award.  Three years later, Butler published Dawn, the first installment of what would become known as the Xenogenesis trilogy. The series examines the theme of alienation by creating situations in which humans are forced to coexist with other species to survive and extends Butler's recurring exploration of genetically-altered, hybrid individuals and communities. In Dawn, protagonist Lilith Iyapo finds herself in a spaceship after surviving a nuclear apocalypse that destroys Earth. Saved by the Oankali aliens, the human survivors must combine their DNA with an ooloi, the Oankali's third sex, in order to create a new race that eliminates a self-destructive flaw in humans--their aggressive hierarchical tendencies. Butler followed Dawn with "The Evening and the Morning and the Night" (1987), a story about how certain female sufferers of "Duryea-Gode Disease," a genetic disorder which causes dissociative states, obsessive self-mutilation, and violent psychosis, are able to control others afflicted with the disease.  Adulthood Rites (1988) and Imago (1989) the second and the third books in the Xenogenesis trilogy, focus on the predatory and prideful tendencies that affect human evolution, as humans now revolt against Lilith's Oankali-engineered progeny. Set thirty years after humanity's return to Earth, Adulthood Rites centers on the kidnapping of Lilith's part-human, part alien child, Akin, by a human-only group who are against the Oankali. Akin learns about both aspects of his identity through his life with the humans as well as the Akjai. The Oankali-only group becomes their mediator, and ultimately creates a human-only colony in Mars. In Imago, the Oankali create a third species more powerful than themselves: the shape-shifting healer Jodahs, a human-Oankali ooloi who must find suitable human male and female mates to survive its metamorphosis and finds them in the most unexpected of places, in a village of renegade humans.
