I reiterate that I don't know anything beyond what's been written. In particular, the Post article (accuracy not being their racket) is not exactly authoritative, and they don't bother to include a copy of the complaint with the article. So we don't know what is left out, nor do we know who the plaintiffs are. We do know who the other named producers were, and they include a respected producer and general manager, Elizabeth Williams, who I assume was GM'ing the show and perhaps exec producing, and other established names. Also Levin, while not an established lead producer, is/was a known quantity.
With that in mind, I have no clue why the Shuberts might have chosen this show other possible alternatives, but these things are often done with an informality that will surprise many. I mention Elizabeth Williams by name because in this scenario if she, as I suspect, was the one making representations, they would likely be accepted without a great deal of scrutiny.
Beyond this, I find it hard to believe that they had only raised $200k plus these investors. (And again, not knowing who the plaintiffs are makes it impossible to guess). Oftentimes, complaints are filed based on a bunch of guesses, because discovery is not available before that. Perhaps the answer will shed more light (and/or a motion for summary judgment).
Obviously there were some things done here that do not reflect positively on Levin or the others involved in the production, but I would not rush to assume everything in the complaint is accurate (or fully accurate), and I certainly would not give the Post credit for much digging beyond reading the complaint and calling one of the producers) who appears to be contradicting at least one assertion. I agree that emails will likely tell much of the tale here; I just don't know what that tale will be.
In order to prove fraud (or misleading investors) the plaintiffs will have to prove that they were told something. If the producers continue to deny ever speaking with them, unless the plaintiffs have some proof, that won't be easy. And without fraud, a lawsuit based on mismanagement is a tough road to hoe. Note, for example, that the plaintiffs would have to show causation (meaning it would have to have been represented in advance). Anyway, in the famous words of someone, we shall see.
