I will be shocked if we get even half the revivals listed. If I remember correctly, most revivals have not returned their investments either, and they are getting more and more expensive to produce. Since most revivals do not have huge runs, even if they return their investments, returns are not dramatic. I can think of Chicago and the Sam Mendes Cabaret as big hits...what else? And we also know what a financial disaster the last revival was for its investors.
Wouldn't an investor be more interested in a new musical, even with the rotten track record, because the upside potential ('this is going to be the next Hamilton or Hadestown or Wicked') is much higher than for a revival. I am not saying that investing in new musicals is a sound business investment -- it probably never has been -- but the upside seems more desirable if you are taking a huge risk to begin with. I admit that, were I extremely wealthy, I would be investing in new musicals, because I love musical theatre, not because I really expect to make a huge profit. 'If I do, I am lucky...and incented to invest more'. Not so sure re a revival, although I would happily sign up to invest only in Evita on that entire list. And it is probably fair to assume that a serious Rachel Zegler injury early in the run would probably derail any likelihood of a profit from that either. Really sucks.
