As anyone who's a bona fide fan of Danny Boyle's generation-defining flick Trainspotting will attest - the cast and the soundtrack were central to the film's cultish appeal. So when the opening bars of Underworld's 'Born Slippy' hit you in the new T2 Trainspotting 2 trailer - look out. Coupled with Ewan McGregor's famous voiceover, we got all the feels.

Picking up 20 years after the original (props to the creators for addressing the passing of time and the fact that people grow age), the flick reunites Renton, Sick Boy, Spud and Begbie for what looks like another drug-fuelled ride. Liek the original, you probably don't want to watch this one with you mum or dad. Given it's been 20 years since we got to know this heroin-addled quartet, we expect there's a lot to catch up on - including Facebook, Twitter and Instagram updates.  We. Can't. Wait.

Watch the trailer below and let us know what you think:
