Interesting.
@troynow - IIRC, you shared this rumor with the board like a year ago or more, and even then you mentioned that Gardiner wouldn't be continuing with the show because of some professional tensions in the production process. And you mentioned that Camille A. Brown would be taking over as director, but so far there hasn't been any other indication of that. You may very well be right, but if so, you know more about it than we do. So I find it a bit funny that you're the one asking us!
It seems to me that the "scheduling conflict" excuse is a little odd. Partly for the reason I just mentioned - the rumor of her departure has existed for more than a year. Also, they haven't even mentioned what the schedule IS for the production, so why wouldn't they just accommodate her schedule if it was a simple matter of her having other projects?
Also, how often do directors get totally dropped from remounts simply because of scheduling issues? I've never even heard of that happening. Usually, if there's a remount of a production that the director can't work into their schedule, don't they just hire members of the production team to recreate the staging? I'll grant you that usually doesn't happen for Broadway shows, but surely the same principle should apply, right? Even when Julie Taymor was fired from Spider-man, they kept her staging and credited her as the original director. And that was way more contentious than mere "scheduling conflicts"
