The "moment" people are referring to never really happened for me as I couldn't wait for it to be over. But the production basically leaves it to the performance of Owen to convey the horror of Room 101 and this just does not work. Requiring an actor to react as if being tortured for an extended period, screaming, etc., is just crass and lacking in any artistry whatsoever. The Owen I saw wasn't a particularly good actor - not sure what Sturridge is doing with the role - and I just felt bad for him having to do that 8 times a week with 2 matinees. It was just terrible and amateurish. In a theatre, there has to be a more effective, creative means to achieve this narrative point than just making an actor scream his lungs out. It was detestable.
