There are roughly 150 Spix's Macaws that make up the giant "2" of the U.S. teaser poster. The number of Spix's Macaws within that formation seems to loosely follow the real-life population of the species left in existence (most of which are kept in captivity around other parts of the world).

This is Don Rhymer's last film as a writer, before his tragic passing.

The boat the characters take up the Amazon River is called "Céu Azul", a translation of Blue Sky, name of the production company.

The anteater Charlie was modeled and named after Charles Chaplin, notably for his mute mannerisms and signature bowler hat.

As of 2018, Ice Age (2002) and Rio (2011) are the only Blue Sky Studios films to have spawned sequels.
