Buck discovers a cave with a three-sided column that depicts past occurrences of mass extinction, and a future one. On one of the sides, a picture of Sid with his three dinosaur "children" from Ice Age: Dawn of the Dinosaurs (2009) can be seen.
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.
