And what stratosphere is Andy Karl in if every show he stars in is a big flop? And LuPone and Ebersole are supposed to be stars but their show isn't turning a profit. And is this a new rule that if an actor with a higher Q rating (Mandy) wants a job on Broadway, they are automatically entitled to it?"
Several people have tried to lay out the facts to you to no avail, but the starkest fact is that the show closed 9/3 and it absolutely did not have to. Big old nobody Oak was standing in the way of grosses that might get them through the rest of the year, so he got replaced. The producers were trying to fix the mess they made by relying on a Hamilton alum that couldn't fill seats. He didn't have to make as much as Groban, he just had to do what Ingrid did and get them through the Summer, after which they had a TV star "name" already rehearsing. Did you really expect the producers to just close the show without trying to do anything to get sales up?
And really, Andy Karl is definitely on another level from Oak, regardless of Broadway box office (multiple Tony noms, that Olivier he won, etc.). However, if they had, say, Jake Gyllenhaal ready, willing, and able to take over in GD, well, I'd kind of assume they'd organize a respectable exit for Andy and usher Jake in right quick.
