My experience is with entertainment financing. What I can add is the producers went with a Hollywood 'star' who could help 'open' the show, and train people to think of Funny Girl outside of Streisand. If/when it's up and running and successful, Beanie will go back to making movies (I would guess her contract will run through the end of the year) and the new lead will be someone who can really sing (or possibly another movie star). So far the producers strategy has worked....lots of people on here, and elsewhere are buying tickets. Reviews will not be great....but producers always knew that. No one can fill Streisand's shoes, and that comparison is inevitable. Ramin is fabulous, but he doesn't sell tickets. The goal here from the producers position is to change the perception/narrative of this property from being a Streisand only show back to a Broadway classic. That's a very hard challenge. No other show in the history of Broadway has catapulted a star into the type of success that Streisand had after Funny Girl, and most likely, none ever will again. The process now is just too different, and the finances just don't allow that any more (at least on Broadway).
Not to take anything away from Streisand.....she has a once in a million years voice, and deserves all she has achieved.
For what it's worth, I would not see this show with Beanie. I enjoy her on film, but she does not have a voice, and there does not appear to be any chemistry between her and Ramin. And that's the key to the show....more so than the singing. That a stud like Ramin would fall for Beanie. I just don't see it...
But for those that are going....enjoy!
