When Ice Age: Dawn of the Dinosaurs hit theaters in 2009, it brought a massive shift to Blue Sky Studios' flagship franchise. Instead of freezing landscapes and retreating glaciers, the herd plunged deep underground into a lush, tropical world ruled by prehistoric beasts. At the center of this blockbuster adventure was a returning core ensemble alongside fresh voice talent that expanded the comedic dynamic.
Understanding who brought these characters to life reveals how a mix of stand-up veterans, sitcom stars, and British comedic actors turned an animated sequel into an $886 million global success.
The Core Herd: Returning Voice Actors
The heart of the franchise remains its mismatched family of prehistoric mammals. Their chemistry grounds the chaotic subterranean setting.
- Ray Romano as Manny: The deadpan woolly mammoth returns as the anxious, protective leader of the herd. Romano brings his signature dry, observational delivery to Manny's stress over impending fatherhood.
- John Leguizamo as Sid: The talkative, accident-prone ground sloth drives the plot by adopting three mysterious dinosaur eggs. Leguizamo uses a distinct, lispy cadence that instantly identifies Sid's well-meaning chaos.
- Denis Leary as Diego: The cynical saber-toothed cat faces an identity crisis in this film as he struggles to keep up with the domestic changes in the herd, prompting him to question his place among them. Leary keeps Diego sharp, cool, and dryly humorous.
- Queen Latifah as Ellie: Manny's woolly mammoth partner is heavily pregnant during the events of the film. Latifah infuses Ellie with warmth, emotional stability, and steady authority when the males panic.
New Additions and Subterranean Characters
The introduction of a lost tropical world required a completely different breed of character, highlighted by an unhinged guide and new rivals. More information regarding the matter are explored by Associated Press.
- Simon Pegg as Buck: Voiced with wild, manic energy by British actor Simon Pegg, this one-eyed, dinosaur-hunting weasel steals the movie. Pegg models Buck's cadence on classic swashbuckling adventurers, giving the character a theatrical, slightly unhinged survivalist persona.
- Seann William Scott and Josh Peck as Crash and Eddie: The mischievous possum brothers serve as chaotic stuntmen for the group. Scott and Peck maintain a rapid-fire comedic timing that highlights their sibling rivalry and reckless bravery.
- Karen Disher as Scratte: The franchise's silent mascot, Scrat, finally meets his match in a flying female squirrel counterpart. Disher provides vocal cues and gasps for Scratte, crafting a hilarious adversarial romance built around their mutual obsession with the acorn.
- Chris Wedge as Scrat: The co-creator of the character and studio co-founder returns to provide the iconic, high-pitched squeaks, gasps, and groans for the ill-fated saber-toothed squirrel.
Supporting Cameos and Cameo Voice Talent
Beyond the primary cast, the production packed the background with notable comedic actors who filled out the dinosaur ecosystem.
- Bill Hader as Gazelle: The Saturday Night Live alumnus drops in briefly to voice a hapless gazelle caught in the food chain.
- Jane Lynch as Diatryma Mom: Bringing her booming, authoritative delivery, Lynch voices a giant prehistoric bird that briefly crosses paths with Sid's adopted brood.
- Kristen Wiig as Pudgy Beaver Mom: Another SNL veteran who lends her distinct comedic timing to a minor background creature in the opening acts.
Behind the Microphone: Recording Process and Production
Unlike many animated films where actors record together in a booth, the principal cast of the Ice Age series recorded their lines separately. Ray Romano, John Leguizamo, and Denis Leary rarely shared a recording space. Directors relied on scratch tracks and vocal matching to ensure the dialogue felt natural.
Simon Pegg recorded his tracks in London while the American cast recorded primarily in New York and Los Angeles. Pegg physically acted out Buck's movements in the studio booth to capture the manic physical comedy of the character, which inspired the animators at Blue Sky Studios to dial up the kinetic action in Buck's introductory scene.
Common Misconceptions About the Cast
Viewers often confuse minor characters or assume certain celebrity cameos took place.
- Peaches' Voice: While Tara Strong voices the baby mammoth at the end of the film, child actors often get credited incorrectly for toddler iterations.
- Rudy the Dinosaur: The massive Baryonyx-inspired antagonist does not speak human language. Vocal legend Frank Welker provided the bone-shaking roars and growls, utilizing animal-mixing techniques rather than spoken dialogue.
