Gary Oldman has revealed most 'The Dark Knight Rises' has been shot in IMAX.

However, the British actor - who reprises his role as Lt. Gordon in the new instalment of Christopher Nolan's 'Batman' franchise - admitted the high resolution cameras did cause some problems on set as all dialogue had to be re-recorded after shooting because they are so loud.

He explained: "[We used it] a fair bit actually. The IMAX camera, it's a strange thing. There's only so much film that you can put through the gate. You get two takes from a roll, I guess.

"The thing is, it's very loud. It's a very noisy piece of equipment and it's quite cumbersome, it's quite a large - you don't hold an IMAX camera, I mean you steadicam it. But of course you have to loop, you have to dub everything you do on the IMAX because you can't hear the dialogue."

Although the franchise is coming to an end, Gary is hugely excited about the final movie -which stars Christian Bale as the caped crusader and Tom Hardy as evil villain Bane - calling it "epic".

He told Collider: "It's the last one, the third one in the trilogy. It's a great story. It's gonna be pretty epic."

'The Dark Knight Rises' is released in the UK on 20 July 2012.
