If it's the 'Dreamgirls' movie, the main characters are Effie White, Deena Jones, and Lorrell Robinson. They are the members of the girl group. Effie has a powerful voice but faces setbacks in the group due to her looks and attitude. Deena is more polished and becomes the face of the group, while Lorrell has her own journey dealing with love and loyalty within the context of the group's rise.
Most likely not. Dream Girls is often a work of imagination, not based on real events. It's designed to captivate audiences with a made-up story and characters.
Honestly, I don't know for sure. It could be based on a novel, a personal experience of the author, or a combination of various elements. Without more specific information, it's hard to say exactly.
Dream isn't based on a true story. It's usually the product of someone's imagination, designed to entertain and engage the audience with a unique and fictional narrative.
