froote said: "Yes she was a slight draw post-Tony (that's why I said barely) but the grosses didn't go super high after she won or anything. Certainly wouldn't be enough to save The Great Comet.
And the grosses went down a lot when Jennifer Hudson left the show. Cynthia did sell some tickets, but for her acclaimed performance in that specific show...just as Alice Ripley and Christine Ebersole sold tickets in N2N and Grey Gardens. It doesn't mean that they would sell a lot for the next show. (I personally think that the majority of tickets sold for War Paint are because of Lupone, not Ebersole).
I was one of the people who purchased tickets for Purple pretty late in the run because I thought it would be silly to miss such an acclaimed show and performance. (And, to be honest, I was disappointed...I thought she vas very good, but not the historic performance that I heard about; and I don't even attribute that disappointment to her...I think Doyle did a great job, that it was much better than the original bloated mess, but that the raw material still wasn't very good, i.e., the book, music and lyrics for the musical...not the original book or even the Spielberg film).
I do think that Erivo has the best chance of becoming a ticket selling star because of her charisma, as well as her talent; but, she would not sell many tickets to TGC. Period.
As for Philippa, per other suggestions, will have no more impact than Oak. She has talent, but IMO has the charisma of a brick. Since both points are also true of Denee, what's the point?
