Giant, illuminated quotation marks enclose the jumble of asterisks and slashes built into Catherine Oddie's stage set at the Old Fire Station. It's a neat way of explaining that Geoff (Jonathan Margree) and Mike (Dan Benoliel) are trying to write a play, only the words just won't come, writes Giles Woodforde.

Geoff, it seems, is rather bemused by the writing game. He cannot understand, for instance, why his piece entitled "the joys of having a foreskin" has been rejected as uninteresting material for the woman's page in the Mail on Sunday. And as for his play, he simply tears his hair in frustration.

Finally a few lines of dialogue are tortured out of the laptop, and actors Dominic (James Eaton) and Beth (Rosie Emanuel) bring them vividly to life. This sequence is extremely funny, for the actors make it very clear that they think the dialogue stinks. But, frustratingly, playwright Jonathan Margree (for he is both the real and the fictional writer) doesn't really develop this idea. Instead he veers off into a routine row between four flatmates about who is responsible for a flood in the loo. Later we're taken off in a more serious direction, as Jonathan Margree explores relationships between writers, actors and audiences.

These very different facets ofWorking Title are effectively put over by The Fat Tree Theatre Company's cast, under Mike Bartlett's direction. That's particularly true of Rosie Emanuel and James Eaton, both of whom provided memorable performances when they were members of Oxfordshire Youth Music Theatre. Jonathan Margree and Dan Benoliel tend to drop the ends of their sentences at times, thus losing vital punchlines. Nonetheless Working Title is an impressive debut piece of work from a young team. Unrequested advice from a crusty old critic: remember the big laughs you received and work on those comedy skills. The world is in sore need of having its funny bone tickled.

Performances continue until Saturday.
