I saw The Jungle last night. It's an extraordinary show, unsettling, upsetting, and immersive in the best ways. We got lucky, scoring tickets in Section C (the Sudan section) with rush tickets. One of the many things I will miss about the Curran when Harry Potter takes over is the theater's willingness to give out excellent seats to rush ticket buyers.
The cast is wonderful. Ben Turner is compelling as Salar, an Afghan refugee who proudly sets up a restaurant in the refugee camp. Ammar Haf Ahmad, as Safi, is an engaging narrator from Syria. John Pfumojena is extraordinary as the young Okot, who is haunted and haunting. Several cast members are actual refugees from the Calais camp where the playwrights, Joe Murphy and Joe Robertson, worked (and set up a theater). The British characters are inherently less interesting, but their interactions with the refugees are important. As the play progresses, its structure grows more predictable, undercutting its impact just a bit. But the actors carry the day, and the cumulative impact of the experience is heartrending.
One other strength of the show: The playwrights' sympathies are clearly with the refugees, but it's not nearly as preachy as I thought it might be. The main refugee characters, Salar and Safi in particular, are three-dimensional people - not just symbols. The camp itself can be a scary place.
Suggestions and warnings: Sitting at floor level, with chaos around me a lot of the time, is the best way to see this show. I basically felt sorry for the folks in the mezzanine. They aren't far away, but their experience must have been far different.
But if you're on the floor, especially with the good seats we had, be prepared not only for loud yelling, swearing and running all around you, but also for gunshots and, yes, a gun waving around during one sequence. (It's not pointed at audience members, but on the floor, you're right there anyway.)
