Next to Normal - Donmar / Wyndham’s

This would be great but Trafalgar Studios no longer exists, would it be in the new Trafalgar Theatre - if so I believe it's booked up with Jersey Boys until next year at least.

Makes sense. The rights holders were supposedly always holding out for a West End opening, rejecting multiple attempts for stagings at venues like Southwark (that would have been a test to see if it was worth transferring), so a new small West End space would be a good fit.

Praying.

I want to say Jenna Russell / Laura Pitt-Pulford already. Both amazing in different ways.

Ooooo yes. All incredible actresses. And yes, with you there - would depend on age.

She'd be one of the (very) few I'd sit through this for again. 

Oooh yes Hannah Waddingham would be great and maybe seen as having an even bigger pull now thanks to the success of Ted Lasso (though maybe that's not been as big of a deal here than it has been over in the US?).

It’s time for Sally Ann Triplett to return to the West End...

I think a lot of these actresses would have been great at playing Diana but suspect they'll cast a younger playing age - Diana should theoretically be late 30s/early 40s so Dearman is a good shout!

you are.

As the mother of two kids in their late teens Diana's age could be anything from the late 30s onwards. Alice Ripley was 45, Marin Mazzie was 50 when she took over the role and, more recently, Rachel Bay Jones too was 50 when she played the part in the Kennedy Center revival.

It's a hugely demanding role vocally, so much that it completely ruined Ripley's voice. Jenna Russell is no powerhouse belter, but she's one of the finest musical theatre actresses in London and in both Sunday in the Park with George and Grey Gardens she held her own against the somewhat more accomplished singers that previously played the same roles. She has also expressed interest in playing Diana on several occasions and five years ago she sang a lovely "I Miss the Mountains" at some event with Jamie Lloyd. I'm sure she'd do something wonderful with the role.

But I agree that Hannah Waddingham would be the most natural and exciting choice, especially after so many years since her last West End outing. Cassidy Janson would be brilliant too! Also, I don't think they really need a recognisable name for Diana, they could always cast some X-factor kids for roles like Gabe, Natalie and Henry and get some real theatre professionals for Diana and Dan.

I saw it on Broadway. Meh. Lots of screaming

My thoughts exactly. Most of the people I know who love it haven’t even seen it!! Still obviously the music holds up for itself.

One of the most dreary nights I've ever spent in a theatre but, if it provides a vehicle for one of our great (age appropriate) musical theatre ladies, then good luck to all involved.

I get the sense that the casting would be carefully done and for the right reasons, as this is more artistic led in and especially as the rights just haven't been given to the UK since...well forever.

Hope that makes sense but from the names that have been discussed on here, anyone of those names would be amazing.

I'm going to throw another in...Rachel Tucker?
