The Dark Knight did what other's couldn't, They brought Neeson back
This surprises me, honestly, as Neeson had announced a retirement from acting for the rest of this year. He'd been working nonstop since his wife's death, and filming on Taken 2
was pushed into 2012 to accommodate his need for downtime.
So while I have no reason to doubt that Neeson will appear in Dark Knight Rises
, I don't expect it to be much more than a scene or two -- unless the retirement announcement was a cover story for his DKR
