Yes, it's based on a real story. Rudy Ray Moore had a remarkable life. He started from humble beginnings and through his own determination and creativity, he developed the Dolemite persona. This character became very popular, especially among certain audiences. The movie shows how he built this character, from writing the stories to performing as Dolemite on stage and in movies. It also shows his struggles with the film industry at the time, including getting financing and dealing with critics.
I'm not very familiar with the specific 'My name is Dolemite story'. It might be a unique personal story. Maybe it's about someone named Dolemite and their adventures, experiences, or how they got that name.
One main theme is perseverance. Rudy Ray Moore had to keep going despite the obstacles. Another is creativity, as he created the unique Dolemite character.
Dolemite is based on a real person and certain aspects of their life. But keep in mind that in the process of making it into a film, some creative liberties were likely taken to make the story more engaging and cinematic.
