Full Ice Age 4 Cast Guide: Every Character and Voice Actor in Continental Drift Explained
By James H. Sterling
At the center of the catastrophe remains the foundational trio that built the series back in 2002. Ray Romano returned as Manfred "Manny" the mammoth, leaning into the anxieties of overprotective fatherhood. Romano brought the same dry, grounded neurosis that defined his live-action television work, balancing broad slapstick with genuine family panic as continental shifts physically tore his family apart.
John Leguizamo provided the unmistakable, lateral-lisp cadence of Sid the Sloth. Leguizamo originally conceived Sid’s distinctive voice after studying real sloths and discovering they store food in their cheek pouches. By the fourth film, that vocal choice was muscle memory, though Continental Drift forced Sid to evolve from an aimless tagalong into a responsible caretaker when his estranged family abruptly abandoned his elderly grandmother in his care.
Denis Leary rounded out the core survivors as the stoic saber-toothed tiger, Diego. Leary played against his signature rapid-fire stand-up persona, offering deadpan sarcasm that served as a foil to Leguizamo’s hyperactive physical humor. The fourth chapter pushed Diego into unfamiliar emotional territory, introducing a romantic counterweight that challenged his predatory, lone-wolf instincts.
