Going by the BI hints, I was also assuming that it meant someone whose personal life DL Broadway fans would bother to know about. I formatted the list in a way that looked terrible once I hit send. Someone else should make a better version.
The original blind item reads: "Broadway A lister will not being attending the awards with the significant other. The person asked the intended to leave their residence, and they did- 2775 miles away. On Sunday it will become clear they no longer together. If voters were made aware of what A-lister was put through (A-lister doesn't even know the full extent of it) they may have actually picked up some hardware."
Going by nominated A-Listers the likely answer is Roth, assuming 3 Women is a shoe in for best play.
PRODUCERS: Marc Platt -- probably going to win for The Band Visit. Thomas Shumacher -- no one cares about him. Jordon Roth -- married and possibly going to win for Angels. Scott Rudin -- probably going to win for Carousel.
Are there any producers who should be added? Roth is a front runner with over 2 'votes' as the A-list producer whose love life falling apart with Ritchie would gain interest and sympathy and possibly have nudged him in the direction of winning rather than losing.
ACTORS and DIRECTORS:
Excluded by the BI poster as mentioned but wrong: Tony Shaloub, Norbert L Butz, Diana Rigg, Patti Murin, Joe Mantello, George C Wolfe, Michael Arden, Marianne Elliot.
Still in the running;
Amy Schumer, LaChanze, Taylor Louderman, Jesse Mueller, Condola Rashad (who is engaged to Sebastian Vallentin Stenhøj), Nathan Lane, Laurie Metcalf, Lindsay Mendez, Tina Landau, Casey Nicholaw, Bartlett Sher.
Amy has been ruled out as 'not Broadway A-list. Lane has been ruled out because Delvin is the nice guy in that relationship. Condola has been ruled out because straight people breaking up does not garner the kind of sympathy that would give her an edge over Jackson. It has been hilarious talking about Tina Landau -- but she isn't actually 'with' anyone we know about.
