Bringing together the two halves of the Tumblr mindset—the one that’s perverse, shameful, and obsessive, and the side that just likes porn—The Wrap is reporting that Teen Wolf star Tyler Hoechlin has joined the cast of Fifty Shades Darker, the sequel to last year’s surprisingly sexless “erotic” drama Fifty Shades Of Grey. The 28-year-old Hoechlin—who plays handsome werewolf Derek on the increasingly inaccurately named MTV show—will appear in the film as author Boyce Fox, an unseen character from the books whose part has been expanded, presumably so that they could cast a werewolf guy to play a dude named Fox. (Many of Hollywood’s most critical casting decisions are often based on puns.)
