John Douglass, owner of the "jacksfilms" YouTube account, was invited to the world premiere of this movie by Sony because he praised it sarcastically since its announcement.

Sony promoted the latter release of the trailer by hosting a press conference in Cannes, the day before the 2017 Cannes Film Festival, which featured T.J. Miller parasailing in. Variety called the event "slightly awkward" and The Hollywood Reporter described it as "promotional ridiculousness."

According to T.J. Miller, this is the fastest produced animated film in history.

The film was shown alongside Puppy, a short film based on the Hotel Transylvania films.

The original title was Emojimovie: Express Yourself.

A week before the film was released, Sony tweeted a controversial promotional picture parodying the Hulu series The Handmaid's Tale (2017). It was immediately met with criticism for being tasteless, considering the content and themes of the Hulu series. Following the backlash, the tweet was deleted.

Ilana Glazer was originally set to play Jailbreak.

This is Steve Wright's second CGI film. He was also in Son of the Mask (2005).

T.J. Miller and Maya Rudolph were previously in Big Hero 6 (2014). A TV series based on that film is scheduled for fall 2017, with Rudolph reprising her role.

Maya Rudolph's second Sony Animation Film, after The Angry Birds Movie (2016). Both of Rudolph's respective characters are both calm characters that try their best never to get angry, only Smiler unlike Matilda is a villain.

The official artwork of the main trio bears a strong resemblance to the final poster for Free Birds (2013).

T.J. Miller and Anna Faris were part of Yogi Bear (2010)'s live-action cast.

Anna Faris' third Sony Animation movie. She was also in Cloudy with a Chance of Meatballs (2009) and Cloudy with a Chance of Meatballs 2 (2013).

T.J. Miller's fifth animated film, after How to Train Your Dragon (2010), How to Train Your Dragon 2 (2014), Big Hero 6 (2014), and Hell and Back (2015).

In the Latinamerican Spanish version, the name of Jailbreak was changed with the name of "Lady Hacker".

Maya Rudolph's second time in an animated film where she plays a villain, after Shrek the Third (2007).
