Christopher Nolan has admitted to feeling emotional during the final scenes of his last Batman outing, The Dark Knight Rises.
The third instalment in his rebooted series, starring Christian Bale as the Caped Crusader, is expected to be the last one for the 41-year-old filmmaker and his leading man.
He told Hero Complex: "I tend not to be too emotional on the 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. Hopefully, reflecting that journey - by all of us who made the films - in the three films together will make it so they have a real span to them, some real heft."
Anne Hathaway, Tom Hardy and Joseph Gordon-Levitt are newcomers to the franchise, while Gary Oldman, Morgan Freeman and Michael Caine reprise their iconic roles.
"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," Christopher added.
"And with these newer characters too, finishing with Anne and all these guys. It was quite touching, I must say."
Christopher is keeping the storyline close to his chest, but says he was searching for a story that would deliver a true finale and close the trilogy in a powerful and definitive way.
