Jim Gordon is a man who has seen all kinds of hell over the years in his beloved city. A man who does things by the book. A man who tries to do what's right for his city. 

In this story, he's a lot older and a lot more experienced in the life of the law. He is also a concerned father who cares about his daughter. He also knows his daughter risks her life being Batgirl. 

For the voice, Gary Oldman and Jonathan Banks' syles really struck out to me. I'm not looking for an impression. I want you to create your own unique voice that would fit the character.
