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.

Background: David Michael Letterman (born April 12, 1947) is an American television host, comedian, writer, and producer. He hosted a late night television talk show for 33 years, beginning with the February 1, 1982, debut of Late Night with David Letterman on NBC, and ending with the May 20, 2015, broadcast of Late Show with David Letterman on CBS. In total, Letterman hosted 6,028 episodes of Late Night and Late Show, surpassing friend and mentor Johnny Carson as the longest-serving late night talk show host in American television history. In 1996 Letterman was ranked 45th on TV Guide's 50 Greatest TV Stars of All Time.
Context: NBC kept Letterman under contract to try him in a different time slot. Late Night with David Letterman debuted February 1, 1982; the first guest on the first show was Bill Murray. Murray later went on to become one of Letterman's most recurrent guests, guesting on the show's 30th anniversary episode, which aired January 31, 2012 and on the very last show, which aired May 20, 2015. The show ran Monday through Thursday at 12:30 a.m. Eastern Time, immediately following The Tonight Show Starring Johnny Carson (a Friday night broadcast was added in June 1987). It was seen as being edgy and unpredictable, and soon developed a cult following (particularly among college students). Letterman's reputation as an acerbic interviewer was borne out in verbal sparring matches with Cher (who even called him an asshole on the show), Shirley MacLaine, Charles Grodin, and Madonna. The show also featured comedy segments and running characters, in a style heavily influenced by the 1950s and 1960s programs of Steve Allen. The show often featured quirky, genre-mocking regular features, including "Stupid Pet Tricks" (which had its origins on Letterman's morning show), Stupid Human Tricks, dropping various objects off the roof of a five-story building, demonstrations of unorthodox clothing (such as suits made of Alka-Seltzer, Velcro and suet), a recurring Top 10 list, the Monkey-Cam (and the Audience Cam), a facetious letter-answering segment, several "Film[s] by My Dog Bob" in which a camera was mounted on Letterman's own dog (often with comic results) and Small Town News, all of which would eventually move with Letterman to CBS. Other memorable moments included Letterman using a bullhorn to interrupt a live interview on The Today Show, announcing that he was the NBC News president and that he was not wearing any pants; walking across the hall to Studio 6B, at the time the news studio for WNBC-TV, and interrupting Al Roker's weather segments during Live at Five; and staging "elevator races", complete with commentary by NBC Sports' Bob Costas. In one infamous appearance, in 1982, Andy Kaufman (who was already wearing a neck brace) appeared with professional wrestler Jerry Lawler, who slapped and knocked the comedian to the ground (though Lawler and Kaufman's friend Bob Zmuda later revealed that the event was staged).
