If you sit and think about “Turbo” for even half a second, it’s difficult not to notice what’s wrong with it, from the formulaic story to its blatant disregard for the rules of auto racing (spoken by a man who doesn’t follow auto racing; that’s how egregious the oversights were). Luckily for the film, it has several other things working in its favor, namely some inspired voice casting, gorgeous design, and smarter than average dialogue. “Turbo” rises above its familiarity and makes for a charming, if predictable, experience.
Theo (Ryan Reynolds) is a snail who, along with his brother Chet (Paul Giamatti), works in the garden outside a suburban southern California house. At night, Theo watches video tapes of race car driver Guy Gagne (Bill Hader), and dreams of being fast like him, a racer named Turbo. One night, while watching the cars on the 101 from an overpass, Theo inadvertently winds up taking part in a street race and ingesting nitrous oxide, which rewrites his DNA and gives him incredible speed. (Warning to children: drinking nitrous oxide will not give you superhuman speed. If anything, it will put you to sleep.) Soon after, Theo and Chet are captured by Tito (Michael Pena), who co-owns a taco truck in a run-down strip mall, and races snails for fun with his fellow mall employees. Once they realize that Theo is actually fast, Tito begins raising money to enter him into the Indianapolis 500, and his new crew of racing snail buddies, led by Whiplash (Samuel L. Jackson), provides support.
