Billing does reflect who TPTB consider their lead for the show -- in this case it would be both Gary and Melina. That would have been true even if they wouldn't have moved the title. Billing is just another form of compensation. It's determined in the contract with the actors. In most cases, the change in opening credits is the easiest form of non-monetary compensation the production could come up with.
I don't see this as a "demotion" because that would have to be agreed upon IN CONTRACT with the affected actors and I don't see anyone doing that. And there's more at play than just the individual actors, union regs are part of it.
More than likely TBTB wanted to move the title up in the credits and, due to contractual restrictions, couldn't put it very first thing.
Yeah, and if it had been that way from the get-go no one would likely think one way or another about it. But doing it three years in is an insult to the younger cast. Everyone knows Gary and Melina are the stars of the show, just as William and Marg are on CSI and Caruso is on Miami. There was no need to move the main title up like that.
I think the most telling aspect of all of this is that Melina is up as far as she is. That an actress gets such high billing on this type of show is a very good thing. It will also be interesting to see how the credits change if/when the other actors go through contract negotiations/renegotiations. To the actors and producers billing is a very delicate subject.
Yeah, I can't imagine any of the actors who are now below the main title are thrilled with it.
