Sony Pictures has released a teaser trailer for Danny Boyle's "T2: Trainspotting" that finds the cast of the 1996 original in a familiar setting, 20 years later.

Yes, that's Ewen Bremner as Spud, Ewan McGregor as Renton, Jonny Lee Miller as Sick Boy and Robert Carlyle as Begbie, standing along a train track.

Based on Irvine Welsh’s own 2002 sequel “Porno,” the film picks up several years after the events of the original, as the characters cross paths again — this time against the backdrop of the porn industry.

"T2" opens Jan. 27, 2017, in the United Kingdom, and arrives the following month in North America.
