Kept in a glass enclosure in a mall, Ivan doesn't care much about anything. He's an easy-going gorilla, interested only in his painting and TV shows. That all changes when Ruby appears. Suddenly, his silverback instincts come into play. The trailer is silent, with exception of sad music in the background. A brief explanation of the book can be read as you observe clips of what Ivan's life is like in captivity. Simplicity at its best, this trailer is sort of a tear-jerker.
