Ewan McGregor is to return to Edinburgh for the world premiere of the Trainspotting sequel, 21 years after the original film made him a star.

The showing of T2 Trainspotting will be held on Sunday 22 January at the Cineworld in Fountain Park.

The film reunites McGregor with director Danny Boyle and original cast members Robert Carlyle, Jonny Lee Miller and Ewen Bremner.

They are all expected to attend the premiere.

T2 Trainspotting comes 21 years after the original film, which followed a group of heroin addicts and explored urban poverty in Edinburgh. It was based on the novel of the same name by Irvine Welsh.

The sequel is based on Welsh’s book Porno.

The trailer for the sequel was released in November and opened with McGregor’s character Mark Renton returning to Edinburgh to see his friends again.
