Oscars 2018 nominee Sam Rockwell has found his new project

Actor Sam Rockwell has signed on to voice a silverback gorilla, Ivan, in Disney's drama The One and Only Ivan. 

Thea Sharrock is directing the live-action/CG hybrid project from a script by Mike White, reported Variety.

Angelina Jolie is producing and voicing an elephant named Stella while Brooklynn Prince is voicing a baby elephant named Ruby.

The book, published by HarpersCollins in 2011, revolves around a gorilla named Ivan who lives in a cage in a shopping mall along with the elephant Stella and a stray dog called Bob.

Ivan does not remember life before the mall, but when the baby elephant Ruby enters his life, Ivan finds himself taking care of her and working on a plan to take Ruby away from their abusive owner.
