Character Analysis
Fee-Fi-Fo-Fum
Giants in film don't come in too many flavors. They're always either chasing young boys down beanstalks or wreaking havoc in a small country town or doing Peter Jackson a solid and agreeing to do some background work in one of his hobbit movies.
But in Fezzik we have a very different kind of giant.
He's huge and bumbling, of course—those two prerequisites are in the first chapter of the Giant Handbook—but he's sweet, and kind, and largely (pun intended) misunderstood. Like Inigo, he helps to kidnap Buttercup, but you can tell he's a little hazy on the details of the mission. You get the sense he would never knowingly cause anyone harm—anyone who didn't have it coming, at least.
We even see this aspect of his personality when he's asked by Vizzini to destroy the Man in Black with his strength. According to Fezzik, he could have accomplished this feat quite easily the second the dude's head came into view (apparently Fezzik has got some mad rock-hurling skillz). But he gives Westley a sporting chance; even his punches don't seem as if they're really intended to land. This guy is built like a fighter, but he isn't one.
We really get to see Fezzik come out of his shell later in the film, when he and Inigo embark on their quest to track down Westley, find and revive him, and then storm the castle. Keep in mind that there is literally nothing Fezzik has to gain from any of this. He doesn't have a princess to rescue, and he has no loved one to avenge. He's going along with it all because Inigo is his friend, and needs his help. It's a very Lenny-and-George situation. Any second now he's going to start asking Inigo when they're gonna get them rabbits.
