Well, it's Lee for me, not the least because I've seen him as Pharoah several times and I believe he'd be a perfect Joseph. Those girls they have dancing with them on ADWD, the others merely tolerate them being there, whereas Lee 'works' them and creates a real on-stage relationship with them in the minute or so he has them there. You almost expect him to carry on snogging them when the cameras stop.
I used to say the same about the professional/amateur thing, beejaybee, but then it's not as though the more experienced actors are exactly rich and famous. Lee, I know, has been overlooked in the past. Maybe the other pros have too. At the end of the day they are still just working men earning a modest wage and who will probably never be more famous than they are now. I think they deserve their chance to be spotted as much as anyone. Being Joseph will be a hugely demanding job and choosing the wrong one could lose the backers and the company an awful lot of money. Better they give the chance to the one they know is up to it, whether or not he's already in the business.
I think what the show does highlight is the fact that even though the boys are all very talented, there is a world of difference between the best people at the local club or theatre group and those working in the world of top class, professional theatre.
