It's all in the casting: Nell Gwyn as Angellica Bianca

More Behn... I was just reading Anniina Jokinen's The Life of Aphra Behn on the Luminarium site:

Nell Gwyn, the famed actress and mistress to King Charles II, came out of retirement to play the role of the whore, Angelica Bianca ('white angel').

I've always been kind of fascinated by Nell Gwyn, with her rags to riches biography and the supposed "Let not poor Nellie starve" deathbed wish of Charles II...

I'm wondering if having such a recognizable personage as Gwyn play Angellica would have further added to Behn's de-demonizing of the whore figure. The fact that Behn chose to keep the original name from Killigrew's Thomaso, too, could mean she liked the "white angel" idea. Any thoughts?
