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.
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.

IN: Shepard was born on November 5, 1943, in Fort Sheridan, Illinois. He was named Samuel Shepard Rogers III after his father, Samuel Shepard Rogers, Jr., but his nickname was "Steve Rogers". His father was a teacher and farmer who served in the United States Army Air Forces as a bomber pilot during World War II; Shepard characterized him as "a drinking man, a dedicated alcoholic". His mother, Jane Elaine (nee Schook), was a teacher and a native of Chicago.

When Shepard first arrived in New York City, he roomed with Charlie Mingus, Jr., a friend from his high school days and the son of jazz musician Charles Mingus. He then lived with actress Joyce Aaron. From 1969 to 1984, he was married to actress O-Lan Jones, with whom he had one son, Jesse Mojo Shepard (born 1970). From 1970 to 1971, Shepard was involved in an extramarital affair with musician Patti Smith, who remained unaware of Shepard's identity as a multiple Obie Award-winning playwright until it was divulged to her by Jackie Curtis. According to Smith, "Me and his wife still even liked each other. I mean, it wasn't like committing adultery in the suburbs or something." After ending his relationship with Smith, Shepard relocated with his wife and son to London in the early 1970s. Returning to the U.S. in 1975, he moved to the 20-acre Flying Y Ranch in Mill Valley, California, where he raised a young colt named Drum and used to ride double with his young son on an appaloosa named Cody.  Shepard met Academy Award-winning actress Jessica Lange on the set of the film Frances, in which they were both acting. He moved in with her in 1983, and they were together for nearly 30 years; they separated in 2009. They had two children, Hannah Jane (born 1985) and Samuel Walker Shepard (born 1987). In 2003, his elder son, Jesse, wrote a book of short stories that was published in San Francisco; Shepard appeared with him at a reading to introduce the book.  Despite having a longstanding aversion to flying, Shepard allowed the real Chuck Yeager to take him up in a jet plane in 1982, while preparing to play the test pilot in The Right Stuff. Shepard described his fear of flying as a source for a character in his 1966 play Icarus's Mother. He went through an airliner crash in the film Voyager, and according to one account, he vowed never to fly again after a very rocky trip on an airliner coming back from Mexico in the 1960s.  In the early morning hours of January 3, 2009, Shepard was arrested and charged with speeding and drunken driving in Normal, Illinois. He pled guilty to both charges on February 11, 2009, and was sentenced to 24 months probation, alcohol education classes, and 100 hours of community service. On May 25, 2015, Shepard was arrested again, this time in Santa Fe, New Mexico, for aggravated drunk driving.  His 50-year friendship with Johnny Dark (stepfather to O-Lan Jones) was the subject of the documentary Shepard & Dark (2013) by Treva Wurmfeld. A collection of Shepard and Dark's correspondence, Two Prospectors, was also published that year.
