Joseph Gordon Lewitt casted in "The dark knight rises"

Finally after months and years of speculatin, Joseph Gordon Lewitt got a role in the upcoming Nolan film "The dark knight rises". He will play Alberto Falcone, son of Carmine Falcone played by Tom Wilkinson in 2005 reboot, "Batman Begins". Let's say how this one turns out to be. Despite my genuine level of excitement i feel kinda numbed because of the possible high number of stories involved.
