With Looper hitting theatres this weekend, it seems like an appropriate time to take a look at the films of Mr. Joseph Gordon-Levitt. Once known only for playing an alien on 3rd Rock from the Sun, I think it’s safe to say that JGL has stepped out from the shadow of his previous work to establish himself as a versatile and capable actor. He slowly built up a resume of interesting independent films over the past decade before eventually making the jump to more mainstream projects including prominent roles in Christopher Nolan’s last two movies. While his filmography is certainly not without blemishes (ahem, G.I. Joe: The Rise of Cobra), at 31 years old he has already turned in quite a few noteworthy performances and I’m guessing there will be plenty more to come. So what would you say is his best film to date? Cast your vote in this week’s poll and then sound off in the comments below.
