As of now, we know that he is going to play, "John Blake", if you don't know who John Blake is, its okay, no one does. If you read "The Dark Knight Rises's" Wikipedia page, it clearly specifies;
"John Blake, a "Gotham City beat cop assigned to special duty under the command of Commissioner Gordon."
Very vague, to say the least. Fans have begun to speculate who he might play, knowing how talented of an actor Mr. Gordon - Levitt is, fans aren't satisfied with his minute role. names like Robin, Nightwing, and even the Joker. ( for Joseph Gordon - Levitt's resemblance to Heath Ledger ) have started to pop up.
I myself believe he isn't just gonna play a "beat cop", Christopher Nolan has worked with him before in Inception. I believe he is gonna play a similar role. Maybe a Robin without the Short shorts, a sidekick to Batman, that isn't at the end of gay jokes. Has he bean assigned to help the Dark Knight in his Final Crusade? Or maybe the total opposite, He has gained The Dark Knights trust and chooses to stab him in the back. We can only speculate, but knowing Christopher Nolan, We won't be disappointed when THE DARK KNIGHT RISES is released, no matter what role he plays.
