Have just read Peter Simpkins' article for The Guardian, 'Is Judi Dench right - are young actors only obsessed with fame?'
It's an interesting debate and I think Simpkins gets it right by coming down on the side of young actors. He suggests the industry is to blame, driving young performers from diminishing opportunities in theatre, towards slightly better chances of survival in television, film and commercials and I can see how one could therefore conclude that there is a mercenary, fame-game element to the contemporary actor's approach to the industry.
Admittedly, there are some poor, deluded, young souls out there who are in it for fame. The culture of reality TV, undoubtedly has something to do with this.
Most reality programs are aimed at a young audience and often focus on transforming the wannabe actor/musician/dancer into a celebrity.
Ironically, reality TV robs the schedules of drama programs which are far more expensive to produce and as a result, there is less work available for the jobbing actor while more wannabes flood the industry.
