“Choose clean living and positive thinking... yeah right,” Mark Renton proclaims over the familiar sound of Iggy Pop’s “Lust for Life”. The sequel for Danny Boyle’s cult junkie masterpiece is on its way, and a teaser trailer with confirmed release dates is out.

However, the Trainspotting sequel promo doesn’t actually provide any new footage, as filming just began last week in Edinburgh. Instead, there’s a supercut with a slightly tweaked opening monologue. The clip does confirm a release date – January 2017 – and the return of the original main cast: Ewan McGregor (Renton), Ewen Bremner (Spud) Jonny Lee Miller (Sick Boy) and Robert Carlyle (Begbie).

T2 is also officially touted as the film title, despite Danny Boyle’s acknowledgement of complications over the name licencing because of a clash with James Cameron’s Terminator sequel of the same name.

Original screenwriter John Hodge has also been linked to the new film, adapting author Irvine Welsh’s novel Porno for the big screen. The novel follow-up begins with Renton making his return to Scotland after a stint as a nightclub manager in Amsterdam. He’d been living off the drug deal money the original gang acquired in the first instalment. While Renton avoids the violent and vengeful Begbie, the old gang are united for a business endeavour in the adult entertainment industry.

Photos emerged last week of filming, where Daniel ‘Spud’ Murphy was seen strutting down a street in the Scottish capital. Given the 20 year gap between the original and this forthcoming instalment, January 2017 couldn't come quicker.
