a. After an incident of Rodney King, the reaction of his case created an uproar. After his trial, all the policemen were not considered guilty. There were still problems with the law system that treated whited and African descents differently thus injustice continued. Later history was being questioned like European achievements and values. Universities got involved to challenge the perspectives within our education. Lastly, America would change to a multicultural society. Thus other voices that were ignored could be heard like social and racial concerns. Later Hollywood would cast African descent actors more. There were new African American filmmakers who made films that reflected social problems but later moved into dramas. Thus in the 1990 more African American worked in Hollywood.
b. I am a sad to mention that I have not watched any movies from the 1990's that was directed by a African descent man.
