New Trainspotting movie:

Images of Renton running along to Underworld.

Renton: "Choose life. Choose a job. Choose a career. Choose a family. Choose the next lane before the intersection. Choose washing machines, cars. At the roundabout choose the right hand turn off.

"I chose not to choose life, or staying on the motorway. I chose something else. And the reasons? There are no reasons when you have a Garmin Satnav."

"Would sir care for a starter? Some garlic bread, perhaps?"

"No, thank you. I'll proceed directly to a trip to York via the Basingstoke Roundabout."

"Ah the hard stuff. As you wish, sir. As you wish."
