The sequel to 1996 hit film "Trainspotting" is officially underway with director Danny Boyle returning at the helm. The original cast members such as Ewan McGregor, Jonny Lee Miller, Ewen Bremner and Robert Carlyle are back while John Hodge, who wrote the script for the original adaptation, is also returning as writer.

The original movie adapted the 1993 novel by Irvine Welsh and told of a group of lower income drug users in Edinburgh, drifting through their lives. Hodge wrote an original script for the project, which takes a look at the characters 20 years after the events of the original movie. Boyle commented, "It's been 20 years since we met these characters and John Hodge's screenplay brilliantly explores what has happened to them and to us in the intervening years."
