For me it was better than the film. It is very understated so I'm not sure how it played in the gods, it perhaps might be better in a more intimate setting, but I was in the stalls and was engrossed.
Zrinka Cvitesic was funny and enchanting as 'girl' and Declan Bennett as 'guy' has the most amazing voice, though he seemed a bit nervous and I don't know if that was all part of the character, if it was it felt a bit forced. Will go back later in the run and see how he is settling in to the role, but he was great nonetheless.
The response at the end was amazing, the cast seemed a bit overwhelmed! The crowd (lot of Irish and Czech) were very enthusiastic and loving.
Part of the set on stage is a bar, which audience members can go and get a drink from before the show and during the interval which I thought was a nice touch.
I thought it was funny, sensitive and a high quality production, I really hope it does well, it will be interesting to see how it fares as there are no 'big' names, and the film wasn't a big commercial hit, but if you get the chance I recommend you check it out.
What??! You're kidding aren't you. ONCE the movie was made for about 160k usd & has made over 9 million usd to date - that's a huge return.
