After War Horse, Curious Incident, and Angels in America, I think Marianne Elliott is a genius. But this proposed production sounds like a trainwreck to me. (Not because of Patti.)
As if the gender-swapping wasn't enough to complicate matters, they are also making it "contemporary". How do you do that without throwing out 70% of the book and a good portion of the lyrics? Answering services, Sazerac slings, TIME magazine, the "scandalous" pot smoking (which was lame 40 years ago), etc., etc.
The problem isn't just with out-of-date references. It works the other way, too. How do you do a "contemporary" Company without including texting, social media, dating apps, etc. Do Bobbi and her married friends not own cellphones? (Well, maybe not Joanne... )
If they have to do that much rewriting/retooling, then it isn't Company any longer. I will be interested to hear how they tackle all these issues. But I'm going to pass on going to London to see it first hand.
