Danny Boyle’s has revealed that a sequel to Trainspotting will be his next project once its four lead actors co-ordinate their schedules.

The British director confirmed that original cast members Ewan McGregor, Ewen Bremner, Jonny Lee Miller and Robert Carlyle would be back for the eagerly-awaited follow up.

Boyle has been promoting his new film, Steve Jobs, at Telluride festival and told Deadline there: ‘All the four main actors want to come back and do it.

‘Now it is only a matter of getting all their schedules together which is complicated by two of them doing American TV series.’

Miller plays Sherlock Holmes in US TV show Elementary while Robert Carlyle has a recurring role on Once Upon A Time.

Boyle described the script, written by John Hodge, as ‘terrific’. It will be based on author Irvine Welsh’s follow up to Trainspotting, Porno, and pick up on the same characters 10 years after the first film.

The director revealed previously that he wanted the sequel out in 2016 to coincide with the original’s 20th anniversary.

He told Playlist: ‘Because it was 1996 when Trainspotting came out. Twenty years, it’s like wow, where did that go.’
