Christopher Nolan thinks superhero movies like `The Dark Knight Trilogy` can`t be made anymore

The acclaimed director said that one of the key reasons he thinks movies like `The Dark Knight` stand out now is because, back when he was making them, he was given the time.

Washington DC: 'The Dark Knight' is considered to be one of the best superhero movie ever made. 

Collectively, 'Batman Begins', 'The Dark Knight' and 'The Dark Knight Rises' make up the 'The Dark Knight Trilogy'.

While speaking in an interview at the British Academy of Film and Television Arts, the acclaimed director said that one of the key reasons he thinks those movies stand out now is because, back when he was making them, he was given the time.

He said, 'That's a privilege and a luxury that filmmakers cannot afford anymore. I think it was the last time that anyone was able to say to a studio, ''I might do another one, but it will be four years. There's too much pressure on release schedules to let people do that now but creatively it's a huge advantage."

"We had the privilege and advantage to develop as people and as storytellers and then bring the family back together."

'The Dark Knight' trilogy was the reboot of the character after Joel Schumacher's movies.

'The Dark Knight' trilogy starred top-of-the-line actors like Christian Bale, Michale Caine, Morgan Freeman, Liam Neeson, Tom Hardy and Heath Ledger among others.

Nolan didn`t particularly discuss the fact that he is well known to prefer film to digital, but he did warn that he would be part of the last generation of filmmakers to 'grow up' with Super 8 film. ''It was a question of putting interesting images together. It's very different for kids today, working with sound," said Nolan.
