How versatile of an actor is Joseph Gordon-Levitt? Let's see: He's gone from playing a troubled teen in Manic, to a lovesick hipster in (500) Days of Summer, to a younger version of Bruce Willis in Looper, to an adult-film addict in Don Jon's Addiction (which he also wrote and directed) - and now, he's hanging out on Sesame Street teaching kids the meaning on the word "reinforce." So, yeah, pretty versatile!
