Research Paper about how the film “The Color Purple” was created

For this research paper, I want to find out about the directors and crew behind The Color Purple. Find out as much as you can about the director and the crew who made the film. Explore this research question:
What did the director intend to accomplish with this film and did he/she feel it was accomplished? if possible, explore any connections between the director/crew and author of the novel. Discuss audience reactions, especially by those who read the book and watched the film. There should be at least 4 secondary sources but no more than 6. Use MLA format. You may use web sites ONLY if they are professional and connected to the film or book.
