As the Edinburgh Fringe rumbles towards its first full weekend and the Olympics gets into full swing, there are still a handful of intriguing new productions opening in London. Chief among them is Lyndsey Turner’s new production of Brian Friel’s 1964 play Philadelphia Here I Come at the Donmar Warehouse, in which the central character, Gar, is played by two actors, in this case Rory Keenan and Paul Reid.

Told from the point of view of a boy with Asperger’s and a fascination with prime numbers, Mark Haddon’s novel A Curious Incident of the Dog in the Night Time was a publishing phenomenon when first released. It’s now being adapted for the National Theatre by Simon Stephens (whose new play for young people, Morning, also opens at the Traverse this week) in a production directed by Marianne Elliott and starring Luke Treadaway.

Theatre Delicatessen present their new project, the Bush Bazaar, which sees them taking over the Bush Theatre and turning it into a kind of performance art market place where you can pick and choose whose work you see and what you spend on it. The artists will be obliged to compete for your coinage.

The Camden Fringe returns for its 7th year, running from the 30th July to the 26th August at various venues around Camden. The first week line-up includes the The Planktonic Players’ staging of John Patrick Shanley’s Savage in Limbo at the Camden Eye Pub.

The European premiere of Kander and Ebb’s Curtains, billed as “a backstage musical comedy whodunit” opens at the Landor Theatre and the Old Red Lion presents two production in repertory, directed by Henry Filloux-Bennett: the by now ubiquitous Henry V and The Revenger’s Tragedy which is now generally attributed to Middleton.

BAC’s Rio Occupation London comes to its conclusion with a three day indoor festival in the V22 Summer Club at the Biscuit Factory which sees the space colonised by installation, performance and Brazilian music.
