I haven't seen the play, but for this at least I actually don't think the ticket prices are particularly high considering the location of the theatre and the calibre of the actors. Jermyn Street has also now committed to paying everyone at equity rates, which is a huge achievement for an unsubsidised theatre of that size. Various other fringe venues can only keep their prices so low because actors and stage managers are not paid properly.
It will be interesting to see if other fringe theatres follow in this policy (and there may be some which do it already). We might see the emergence of more of an off-Broadway set of theatres that charge higher prices but produce their own work and pay performers (with the result that actors eschew the other fringe venues). There is definitely a place for venues like the Finborough which allow emerging companies to put on large cast plays (often excellent), but I have always thought that it would be nice to have more independent, small theatres that produce their own work and pay proper rates.
Saw this last night and, as neilvh said, the main attraction is seeing some great acting in a very intimate environment.
I didn't know anything about Strindberg as a person, so this was an interesting insight (assuming it's based in fact). It's a very traditional play - it's not breaking any ground or doing anything you haven't seen a thousand times before. And there were times when the writing felt quite creaky. But as a character study (of him at least - the three women were stick figure cliches) it was engaging, there were some interesting themes explored intelligently and the two main actors really sold it. The wavering of his mind was done really well, to the extent that I started seeing his point of view and half-believing in demons and succubi, etc, and I liked the fact that I never quite knew if the wives were a delusion or really visiting him. And his problem with women (and his other prejudices) was conveyed very well, so you recoil from him and feel a bit grubby while still finding him sympathetic.
Worth 90 minutes of my life, would probably have over-stayed its welcome if any longer.
The Jermyn Theatre has its problems, but its geographical location is firmly West End (which costs) and if it moves up a couple of notches by having actors such as Jasper Britton well... the punters are going to have to pay something for it. I am not sure the theatre has any public money and with the 70 seats or so it has it is dificult to see how it actually breaks even.
It is really a study of madness, which is something I tend to find pretty tedious and this lacks any real plot or drama. For a play about a playwright, I was expecting more insight into Strindberg than I felt was there.
Jasper Britton didn't have the charisma I felt was required and because of that I was never really sold on it, although maybe there just wasn't enough good material in the script for him to work with.
