Angelina Jolie's daughter Shiloh influenced her to take the role in "The One and Only Ivan".
Jolie told ET's Nischelle Turner, "Well, Shiloh years ago told me that she had read a book that she loved and she wanted me to read it".
"I read it on my own and then we looked at some of it together and we talked about why she loved it".
"Then, I inquired if it was being made -- as you do -- into a film, and I found out that it was kinda in the works but kinda hadn't [been] figured out."
Angelina Jolie is the voice behind elephant named Stella in "The One and Only Ivan".
This movie is about a gorilla who was kept in a cage for 20 years. He tried to escape together with Stella.
