Garrett Hedlund

'Love Don't Let Me Down,' which is the original title of 'Country Strong,' was just as difficult emotionally as 'Tron' was physically. I play a country singer that basically gets on tour with Gwyneth Paltrow's character, who is one of the biggest country stars out there, and she's fallen down too many times and it's an intense emotional story.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
