Notorious- In theatres tomorrow

So Notorious hits theatres nationwide tomorrow. Im Definitly gna be there to watch it. Im curous though on how they can make a movie about someone who has passed? Yeah im sure that Puff, Faith, and his mother knew Big inside and out, but wouldnt it be great to watch a movie from his point of view? I wanna know how the real B.I.G conquered his dreams...i dont know, i guess well never know right? Now that movie is released i wanna see wat there gonna do about Pac.
