• Many of the performers that followed the show from workshop to opening offered suggestions and ideas to further their characters. Shortly after opening, an argument was mentioned in the New York Times concerning just how much creative input the cast had. Eyen denied this later (in a written statement, co-signed by Henry Krieger) saying: "The cast worked from a printed script. Improvisations, when they were used, were to find the rhythms and essences of the actors in order to enhance their roles. These improvisations were not used to create the characters, words or music of Dreamgirls." Cleavant Derricks, however, insisted: "Tom knew what he wanted but he needed the words. We'd get up in the workshop and improvise and create the characters. Tom would write down what we were saying."
  • There were occasional disagreements between Bennett and cast members and it has been said that relations were often icy.
  • Vanessa Williams was considered as a replacement for Deena during the original Broadway run.
  • Roz White left the 1997 tour because she had vocal problems due to the stress of getting through "And I Am Telling You I'm Not Going."
  • Linda Leilani Brown travelled to New York to audition for Sophisticated Ladies. She auditioned as Linda Brown. After she sang, she was sent to the Imperial Theatre to audition for Dreamgirls. The 'Leilani' was added to her name to make her sound more exotic.
  • Phylicia Rashad (then Ayers-Allen) was the original understudy for the role of Deena. When Sheryl Lee Ralph went on vacation and Phylicia was not asked to fill in, she quit (according to her, she tendered her resignation directly to Bennett in very direct words). She felt that the role was perfect for her and that she was ready to take it on eight times a week. However, Linda Leilani Brown was brought in to perform the role following the closing of the first national tour. Whatever the circumstances of the decision, Ms. Raschad seems to have overcome that career setback.
  • Arnetia Walker is the only performer to actually perform all three roles (Deena, Lorrell, and Effie) on stage in any of the original or touring productions. Other performers were listed as understudies but Ms. Walker is the only actress to perform them.
  • It has been staunchly denied by its creators that Dreamgirls is based on the story of Diana Ross and the Supremes. Reading the article on this website about the gestation of the show, one assumes that it is mere coincidence (since the show started out more in the Valley of the Dolls vein with three roommates' trials and tribulations with different facets of show business). However, Diana Ross saw more than a passing resemblance to her life when she attended the show on Broadway. She walked out before the end of act one.
  • Diana Ross covered the song "Family". She apparently did not realize its source because she is not very fond of the show's plotline and subject matter.
