I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Dreamgirls Movie plot: Backstage at an R&B amateur talent show at the Detroit Theatre in 1962, young car salesman Curtis Taylor Jr. meets a black girl group known as "The Dreamettes": lead singer Effie White and back-up singers Deena Jones and Lorrell Robinson. Curtis presents himself as The Dreamettes' new manager and arranges for the girls to become backup singers for popular R&B singer Jimmy 'Thunder' Early. Curtis soon starts his own record label, Rainbow Records, out of his Detroit car dealership, and appoints Effie's brother C.C as his head songwriter. When their first single fails after another pop group releases a cover version, Curtis, C.C, and their producer Wayne turn to payola to make Jimmy and The Dreamettes mainstream pop stars. Offstage, Effie becomes infatuated with Curtis, while the married Jimmy begins an affair with Lorrell. However, Jimmy's manager Marty grows weary of Curtis' plans to make his client more pop-friendly and walks out. When Jimmy bombs in front of a white Miami Beach audience, Curtis sends Jimmy out on the road alone, keeping The Dreamettes behind to headline in his place. Feeling that Effie's curvy figure and distinctive voice will not attract white audiences, Curtis appoints the slimmer and higher-voiced Deena lead singer and renames the group "The Dreams". With the aid of new songs and a new more glamorous image, Curtis and C.C. transform The Dreams into a top selling mainstream pop group by 1965. However, Effie begins acting out, particularly when Curtis' affections also turn towards Deena. Curtis eventually drops Effie (who has just learned she is pregnant with Curtis' child) from the group, hiring Michelle Morris, his secretary, to take her place beginning with their New Year's Eve debut in Las Vegas as "Deena Jones & the Dreams". Despite Effie's defiance and desperate appeal to Curtis, he, C.C., and The Dreams leave her behind and forge ahead to stardom. Seven years later, Effie has become an impoverished welfare mother, living in inner-city Detroit with her daughter, Magic.... My question: What is the name of Effie's brother?
The answer to this question is:
Curtis
