Trainspotting 2 teaser has a lust for life

A teaser trailer has been released for Trainspotting 2, which harkens back to the original in a variety of ways.

It shows the original crew, Renton (Ewan McGregor), Spud (Ewen Bremner), Sick Boy (Jonny Lee Miller) and Begbie (Robert Carlyle) standing on a platform as a train passes. And, of course, Iggy Pop's distinctive Lust For Life plays in the background.

That's about all it shows, but it may be enough to wet the whistle of fans of the original.
