Biopics are a genre by themselves. When a writer is trying to adapt a real person's life to the big screen, there is a necessity to bring the man/woman to life by portraying his mannerisms, his looks and his dialect as closely as possible. 

And it becomes the actor's job to 'become' that person, however refraining from mimicking them.
