Everybody needs to brush up on their homework from time to time. Even years or decades after graduating college with a degree that's essentially the equivalent of majoring in being undecided (apologies to fellow Communications majors), that learning experience still comes back occasionally to affect the present. But sometimes, the homework is a little less academic and a little more addictive, allowing a lucky few to enjoy a particularly enviable brush-up session. As with many cases, Henry Cavill, who plays the lead role of Geralt on Netflix's The Witcher, is one of those lucky people.
