Theatre review: East is South

PREVIEW DISCLAIMER: Hampstead Theatre invites the critics in next week.

After The Invention of Love saw Hampstead Theatre's main stage get caught up in classical analysis for a couple of hours, Beau Willimon's East is South threatens to do the same thing but with theology. In a secretive facility somewhere under an American desert, international teams of computer coders have been developing "Aggie," an AI more powerful than any seen yet - one that may not only end up passing for real human intelligence, but supercede it. Developers work in pairs and no new code can be approved without checks by multiple teams, but for all the security checks there's been a breach that might see Aggie escape onto the Internet. Lena (Kaya Scoledario) and Sasha (Luke Treadaway) are one of the teams working on the kill switch, the code that can shut down the programme if it gets too powerful and out of control.
