Danny Boyle, director of the new movie '127 Hours,' told Cinematical that the long-discussed sequel to his breakthrough film 'Trainspotting' will get made, but he is waiting for the right time to make it. "It will happen, I think," Boyle said Friday during an interview in Los Angeles. "I mean, we'll approach them all again about it, but it will depend on what place they're all at. We have a very strong idea that it would be a wonderful thing to reapproach, to do again, when they have aged clearly into a mid-life kind of crisis, basically. They're not quite there yet, I don't think."

'Trainspotting' was based on the book of the same name by Irvine Welsh, who subsequently wrote a follow-up entitled 'Porno.' Boyle agreed with 'Trainspotting' star Ewan McGregor, who has said in previous interviews that Welsh's book would be the only source material for a possible sequel, but it may not yet be the right story to tell in order to revive the characters.

"He's right of course that the book, 'Porno,' is not a great book in the way that 'Trainspotting,' the original novel, is genuinely a masterpiece, I think, as a piece of writing. But we have been doing some work on it, and it's got potential, yeah, for sure. And when the moment's right, I think we will approach it."

Looking back at the film, Boyle said that particularly in retrospect, he felt a little bit like he was capturing lightning in a bottle by bringing all of these promising young performers together, and then enabling them to create the characterizations and relationships that have since become iconic. "They were brilliant, and it's quite rare when you get a cast that's that different," he reflected. "They're so different and yet they kind of jell together like they're all in the same film. It's weird. And yet, they're all very extreme performances."

He continued, "I remember Ewan saying to me, 'Am I doing enough?' Because he said, 'I'm watching Begbie and I'm watching Spud and they are acting so much that it's like this huge Roman-candle firework going off, and I'm not doing anything.' I said, well, you are doing something. I said, you will hold it together, you know, I think you will be our way through it, really."

Boyle also said that he thinks the delay will rejuvenate the material and create a different context in which to explore the characters. "It will be nice because I hope that the thing that will happen then is that it won't be just cashing in," he speculated. "It will be a very deliberate and imaginative reapproach to it, saying, how can you use something that's become a cult hit where people know so much about it, [and] how can you reapproach it other than just making it a sequel, which is just cravenly a business decision."

"This is an imaginative thing to look at these guys, who you kind of fell in love with and a whole generation fell in love with in a certain kind of way, and then you see them again and they've aged, just like we all do," he observed. "And then it becomes about that, and I think that would be really nice."
