Ethan the mammoth and Louis the mole hog, two main characters from Ice Age: Continental Drift (2012) are spuriously absent from this film with no mention of them at all. In this film Peaches is engaged to another mammoth named Julian who only has three lines in Drift. Louis only has a brief silent cameo for a few seconds at the beginning of the film.
The drawing of Sid (John Leguizamo) that Sid gave Brooke (Jessie J) is the same drawing that he draws on the wall in the first film.
Not counting spin-offs, this film makes Ice Age the first ever computer animated theatrical film franchise to feature five installments.
This is the longest movie in the franchise.
Sid speaks without a lisp for the first time in one of the scenes.
The film was originally scheduled for a July 15, 2016. However, the release was delayed to July 22, to avoid competition with Ghostbusters (2016). Ultimately, both films underperformed at the box office.
