It may seem as if every young British actor went to Eton or Harrow, to paraphrase the Arts Council chair Sir Peter Bazalgette (who, mind you, was educated at the none-too-shabby fee-paying Dulwich College). But one of the hothouses of acting talent in the UK is located in the rather less hallowed northern fringes of Nottingham - The Television Workshop. And it can sometimes feel like it has supplied actors to every cult British film and TV show that didn\'t require a cut-glass accent.

One such actor is the 28-year-old Nottingham native Joe Dempsie. "Founded in the Eighties when Central Television had studios near Nottingham, it started as a focus group to test kids\' programming out on real kids," he explains, "and then evolved into training the kids actually to be in the shows.

"There was a gap in the market for a show about teenagers that featured actors that were pretty much the age they were supposed to be playing," says Dempsie, laughing, "not like James Van Der Beek in

. It also seemed to be the first show of its kind that didn\'t patronise its audience. Yes, there were tales of misbehaviour but they weren\'t consequence-driven. My character was the biggest drug-taker of the lot but that wasn\'t what killed him - it was a brain haemorrhage. It didn\'t preach and people identified with that."
