- Acclaimed Flop: The film got positive reception but flopped completely in the States, likely due to being released in August and its accompanying marketing campaign making the film look like a rehash of the first movie.
- The Cast Showoff: Josh Gad and Rachel Bloom do their own singing for Chuck and Silvers opera number.
- Jossed: It was heavily speculated that the pigs were secretly using the birds during their Enemy Mine and were plotting to double cross them in the third act. This turned out to not be the case, as the truce is entirely genuine and the two species even put aside their war permanently in the ending.
- Milestone Celebration: The film was released on the franchise's tenth anniversary.
- Name's the Same: By sheer coincidence, the name of Zeta's residence - Eagle Island - also happens to be the title of a video game likewise themed around birds that was released about a month prior to the movie's US premiere.
- Non-Singing Voice: Suzanne Walters provides Bombs opera voice during the aforementioned number.
- The Other Darrin: Terence's grunts are provided by Nolan North instead of Sean Penn, likely because of Terence's role being Demoted to Extra.
- Playing Gertrude: Tiffany Haddish is only twelve years younger than Leslie Jones, despite playing her daughter.
- Release Date Change: The film's North American release was shuffled a few times. It was originally scheduled for September 20, 2019, then moved to September 6, then August 16, and then moved once again to August 14, but was eventually released a day prior on August 13.
- Short Run in Peru: The film was released in UK theaters on August 2, 2019, little less than two weeks before its release in the United States (August 13th).
