The trailer for romantic threequel Before Midnight has been released .
The married couple are on holiday in Greece and almost two decades have passed since their first meeting on that train bound for Vienna.
There's an unmistakeable charm and an almost Woody Allen-esque feel to the trailer, but it could also be the holiday from hell. There's the promise of comedy, romance, drama: pretty much like a real relationship.
Check out the trailer now:
Before Midnight hits the UK on 20 June 2013.
