I think the casting is great. If it all works out it has the possibility to be huge with West End, Broadway, German, tours galore etc - or it could go the Beaches, Amelie, Viva Forever route and not work. Fingers crossed it is a big gigantic HIT new show!!
For those who may be interested in one of the songwriters for the musical, Kate Miller-Heidke, she's a really interesting singer, songwriter and actress who has combined pop, folk and opera throughout her career. She's also won a Helpmann Award (Australia's Tonys) for Best Original Score for 'The Rabbits' so the musical should be in safe hands. Her most recent album is a live album with the Sydney Symphony Orchestra. Here is one of my favourite songs of hers, O Vertigo!, from her show with the Melbourne Symphony Orchestra (even if she forgets some of the words). It'll be really interesting to hear what she comes up with for 'Muriel's Wedding'.
These days she's more known here as a children's performer and Playschool presenter, although she does the occasional adult acting job too. I last saw her two years ago in Children of the Sun.
How was she?
She was fine. Even though I'm really not a fan of the moaning Russian plays.
The presenters of Australian Play School have include many well respected actors - you mentioned Philip Quast, but also Simon Burke, John Waters, Georgie Parker, Jay Laga'aia , Ruth Cracknell and Colin Friels amongst others.
