Ewan McGregor thinks a 'Trainspotting' sequel would be ''extraordinary''.

The 44-year-old actor starred as heroin addict Mark Renton in the 1996 movie and has revealed he would love the opportunity to make a sequel with director Danny Boyle.

He said: ''I think it might be extraordinary to see a sequel 20 years after the original.''

Ewan admitted he'd already spoken to the acclaimed director about making another 'Trainspotting' movie, but insisted he doesn't know whether it will happen.

He shared: ''I would be up for it, I've said that to Danny.

''I haven't seen any script yet or anything and I don't know if there is one. There is a big idea that it might happen but I don't know that it is happening, I really don't.''

Ewan was initially reluctant to make a sequel, but said he's come round to the idea over the last few years.

He reflected: ''I just think I've changed my opinion about it. We've all moved on and there's a lot of water under the bridge.

''I miss working with Danny. I did some of my best work with him and he is, to date, one my favourite directors I've ever worked with because he's such a brilliant director.''
