`Trainspotting` sequel to begin filming in May

Los Angeles: Ewan McGregor has confirmed that he long-awaited sequel to "Trainspotting" is set to begin filming at the end of May.

The sequel comes 20 years after the original cult classic film and a decade after Irvine Welsh wrote his follow up novel Porno, reported Collider.

"It's been 10 years since Irvine Welsh wrote the sequel novel, Porno, so it's been a long time, a lot of speculation. For me, too! 10 years ago, I didn't want to do it; I wasn't ready to do it. Also, there was no script," he said.

"The script only arrived very recently, which was really, really, really good. I think, if that had not happened, none of us would be into it. I think we're all sort of somewhat protective of what Trainspotting means to people, and what it means to us."
