An extinct mammal that looked just like Scrat, named Cronopio dentiacutus, was discovered some time after the first film was released.
The Gastornis from the sequels don't appear to invoke the same Carnivore Confusion among herbivores as other carnivores in the series do. Skip ahead several years and it's discovered that Gastornis was actually a herbivore.
Baby Name Trend Starter: The year after the first film came out, Diego, the name of one of the main animal characters in the movie, jumped from the 140th most popular baby name in the United States to number 83.
Cash-Cow Franchise: Blue Sky Studios produced thirteen features, five of which are Ice Age films; of their six short films, three of them are Ice Age spinoffs. And in spite of increasingly poorer reviews, they've earned progressively more money, at least until Collision Course.
For the European French dub, there's Gérard Lanvin as Manny, Élie Semoun as Sid and Vincent Cassel as Diego.
For the Japanese dub, Sid is voiced by the famous comedian Hikari Ōta and Diego is voiced by veteran actor Naoto Takenaka for the first three films.
The Latin American Spanish dubs have actor Jesús Ochoa as Manny, actor/comedian Carlos Espejel as Sid, and actress/singer Angélica Vale as Ellie. The first film also has Sergio Sendel as Diego.
The Brazilian Portuguese dubs of all five movies have Diogo Vilela as Manny, Tadeu Mello as Sid and Marcio Garcia as Diego, with The Meltdown and Dawn of the Dinosaurs having Cláudia Jimenez as Ellie, while Collision Course has Ingrid Guimarães as Brooke and Whindersson Nunes as Roger.
In the Finnish dub of the Ice Age sequels, Crash and Eddie were voiced by Jukka Hildén and Jarppi Leppälä from The Dudesons.
Creator's Pest: You get a sense that Shira is this. After being a supporting character in Continental Drift, she's entirely absent in the The Great Egg-Scapade short (with a Hand Wave from Diego explaining her absence), and in Collision Course, she's just a Living Prop. Come The Ice Age Adventures of Buck Wild, she's hit with full-fledged with Chuck Cunningham Syndrome (along with Brooke).
Cross-Dressing Voices: Crash and Eddie are both voiced by women in the Japanese dub.
Descended Creator: Blue Sky founder Chris Wedge, who directed the first film and executive produced the sequels, voices Scrat in all media. He also voices one of the dodos in the first movie.
Flip-Flop of God: The supplementary material of the second movie can't decide to which species of marine reptile Cretaceous belongs to. The Essential Guide refers to him as Ichthyosaurus while online game Ice Age Village and official magazine Ice Age: Animal Collection identifies him as Metriorhynchus. Given his resembles to the latter species, he's most likely Metriorhynchus.
Franchise Zombie: While the films have done fairly well financially, critical consensus is that this movie should have remained a standalone film and that every succeeding sequel is less creative than the previous one.
Non-acting example: John Powell replaced David Newman (who wrote the score for the original film) to compose the score for the first three sequels. Surprisingly, Powell did not return to score the fifth film, with John Debney taking over instead. For Adventures of Buck Wild and Scrat Tales, Batu Sener took over; as a former protégé of Powell's, Sener's score for Adventures of Buck Wild quotes a few of Powell's leitmotifs from the franchise.
Squint the rabbit was originally voiced by Aziz Ansari in the fourth film. In the Great Egg-scapade Easter special, he was voiced by Seth Green instead for unknown reasons.
In the Latin American Spanish dub, Sergio Sendel, who voiced Diego in the original film, rejected an offer to return for the second film because the producers didn't want to pay him the offer he expected. As a result, he was replaced by regular VASebastián Llapur for the rest of the franchise.
In the Japanese dub of the fourth and fifth films, Unshō Ishizuka replaced Naoto Takenaka as Diego. He was recast once again for Adventures of Buck Wild due to Ishizuka's 2018 death.
The Brazilian Portuguese dubs of Continental Drift and Collision Course have regular voice actress Carla Pompílio replacing Cláudia Jimenez as the voice of Ellie.
Zigzagged in video games. John Leguizamo always comes back to come in and do Sid while Chris Wedge always voices Scrat. Denis Leary reprises his role as Diego for each game except the Dawn of the Dinosaurs one, where Rick Pasqualone fills in. Debra Wilson fills in for Queen Latifah as Ellie in the video game for The Meltdown, but Queen Latifah reprised her role for the others. And Ray Romano reprised his role as Manny for all of the video games except Ice Age: Continental Drift - Arctic Games, where Keith Ferguson fills in, and Ice Age: Arctic Blast, where Jeff Bergman fills in.
With the exception of Simon Pegg as Buck, every returning character is recast in Adventures of Buck Wild.
Playing with Character Type: Denis Leary as Diego. Like most characters played by Leary, Diego is not always the nicest guy who is also afraid to show his emotions in fears of being seen as "unmanly". Unlike most characters played by Leary, though, he prefers to stay calm and collected while mostofLeary'scharactershaveaHair-Trigger Temper.
Promoted Fanboy: Josh Peck was a fan of Ice Age before being cast as Eddie. He was very excited to be a part of the saga. Queen Latifah was also a fan of the original film before she was cast as Ellie in the same film.
