Ewan McGregor considers Trainspotting 2

Ewan McGregor says he's considering starring in a sequel to Trainspotting.

The actor has previously said he would not reprise his role of Renton in the cult movie.

But he says he is now considering the sequel, after reading the book, Porno, by Irvine Welsh.

He said: "I thought it was best left as it was because it would be terrible shame if it didn't live up to expectations.

"Then I read the book and said 'Oh come on it's fantastic'. It's interesting to find out what the characters are up to."
