(BANG) -Christopher Nolan will ''never'' make another 'Batman' movie.

According to the director's wife and producing partner Emma Thomas, there is ''no possibility'' of the filmmaker - who has helmed 'Batman Begins', 'The Dark Knight' and forthcoming film 'The Dark Knight Rises' - taking charge of another motion picture containing the superhero because he wouldn't be able to get ''excited'' about a fourth film in the franchise.

She said: ''No, that's truly a never. I can't imagine a world in which he would ever want to come back.

''At a certain point it's fun to go off and do something different, you know. We've spent almost 10 years of our lives making Batman films. He was very excited about this film, and the story that he'd come up with, but I just cannot imagine that he would get that excited about another version of the same thing.''

Emma believes a third movie in the series still feels like part of the original movie, but she insists doing a fourth motion picture in the franchise wouldn't be appealing to Christopher because the story will have veered so far away from 2005's 'Batman Begins'.

In an interview with SFX, she added: ''The great thing about a trilogy is that it feels like you've got a beginning, a middle and an end. It's like an extended version of a regular film.

''Once you get into a fourth film then it's just episodic, and I just can't see him getting excited about making another film where basically you're just wheeling in different villains.''

'The Dark Knight Rises' opens in cinemas in July 20.
