Christopher Nolan is "wary" of 3-D.

The director admits he still doesn't think the technology has been advanced enough to properly suit cinematic releases but is considering giving in to fan demand for the style to be used in the next 'Batman' movie.

He said: "Until we get rid of the glasses, or until we really massively improve the process, I'm a little wary of it.

"But we'll be looking at it, and if that's what audiences are demanding from blockbusters - and we're making blockbusters - then it's something we'll address."

Although considering using it himself, Christopher isn't a fan of 3D movies and believes a good movie should be so "well-shot and well-projected" that they don't need to use the new filming technique.

He explained: "I'm taking a bit of a wait-and-see attitude towards 3D. It's come and gone many times over the years. I don't particularly enjoy watching films in 3D films because I think that a well-shot and well-projected film have a very three-dimensional quality to it. So I'm somewhat sceptical of the technology."

Filming of the currently unnamed movie - which will star Christian Bale in the title role and be Christopher's last for the franchise - is due to start in March 2011.
