as the legal secretary to Foxx’s character. Though Barrino emerged as an early frontrunner for the part, Hudson was eventually selected to play Effie, leading Barrino to telephone Hudson and jokingly complain that Hudson "stole [Barrino's] part." Hudson was required to gain twenty pounds for the role, which marked her debut film performance. In casting Hudson, Condon recalled that he initially was not confident he'd made the right decision, but instinctively cast Hudson after she'd auditioned several times because he "just didn't believe any of the others." After Hudson was cast in November 2005, the Dreamgirls cast began extensive rehearsals with Condon and choreographers Fatima Robinson and Aakomon "AJ" Jones, veterans of the music video industry. Meanwhile, the music production crew began work with the actors and studio musicians recording the songs for the film. Although rehearsals ended just before Christmas 2005, Condon called Hudson back for a week of one-on-one rehearsals, to help her more fully become the "diva" character of Effie. Hudson was required to be rude and come in late both on set and off, and she and Condon went over Effie's lines and scenes throughout the week. Loretta Devine, who played Lorrell in the original Broadway production, has a cameo as a jazz singer who performs the song "I Miss You Old Friend." Another Dreamgirls veteran present in the film is Hinton Battle, who was a summer replacement for James "Thunder" Early onstage and here portrays Curtis' aide-de-camp Wayne. Principal photography Principal photography began January 6, 2006 with the filming of dance footage for the first half of "Steppin' to the Bad Side," footage later deleted from the film. The film was primarily shot on soundstages at the Los Angeles Center Studios and on location in the Los Angeles area, with some second unit footage shot in Detroit, Miami, and New York City. The award-winning Broadway lighting team of Jules Fisher and Peggy Eisenhauer were brought in to create theatrical lighting techniques for the film's musical numbers. Beyoncé Knowles elected to lose weight to give the mature Deena Jones of the 1970s a different look than the younger version of the character. By sticking to a highly publicized diet of water, lemons, maple syrup, and cayenne pepper (also known as the Master Cleanse), Knowles rapidly lost twenty pounds, which she gained back once production ended. Shooting was completed in the early-morning hours of April 8, 2006,
