Christopher Nolan got a "lump" in his throat when he finished shooting 'The Dark Knight Rises'.

The acclaimed filmmaker is currently in the post-production stage for his third and final outing as the Batman director, and he admits he found it hard to keep a lid on his emotions while shooting scenes with Christian Bale, who plays the titular character.

He said: "I tend not to be too emotional on set. I find that doesn't help me do my job, but you definitely get a little lump in your throat thinking that, 'OK, this is going to be the last time we're going to be doing this.'

"It's been quite a Journey. It was pretty emotional as we would finish these characters and say goodbye to Alfred for the last time and say goodbye to Commissioner Gordon and eventually with Christian, fairly close to the end, saying goodbye to Batman. It was a big deal."

Oscar-nominated Christopher was particularly glad to get Tom Hardy on board to play the villainous juggernaut Bane because he is a "physical actor" who is willing to "transform" himself for a part.

He added to the Hero Complex blog: "Getting an actor like Tom Hardy to take it on, you know you're going to get something very special.

"Tom is somebody who really knows how to put character into every gesture, every aspect of his physicality in the way that great actors can. He's a very, very physical actor. He transforms himself and it's there in every movement."
