The new trailer for 'The One and Only Ivan' boasts a really impressive cast. The animal characters are voiced by Sam Rockwell, Angelina Jolie, Helen Mirren, and Danny DeVito, and Bryan Cranston appears in one of the live-action roles.

The film is based on the award-winning book by Katherine Applegate. It's a story about silverback gorilla who has spent almost his entire life in captivity, but eventually learns there may be more to life than his current environment.

Here's the official synopsis:

Ivan is a 400-pound silverback gorilla who shares a communal habitat in a suburban shopping mall with Stella the elephant, Bob the dog, and various other animals. He has few memories of the jungle where he was captured, but when a baby elephant named Ruby arrives, it touches something deep within him. Ruby is recently separated from her family in the wild, which causes him to question his life, where he comes from and where he ultimately wants to be.

'The One and Only Ivan' will be available on Disney Plus on August 14.
