The interview between the two is an attempt to find out the real motives and intentions behind Rick's awful crime; a crime which we don't know the details of until very near the end of the play. Through Gloria's questioning we learn about the catalysts of the crime, and the general views and opinions of Rick, but it is not until 2 minutes from the end that we find out exactly the part he played in it.
The set instantly captures your attention. Since the entire play takes place inside the big glass box, you can only hear what the actors are saying when a recording device is switched on. It was very unsettling at the beginning of the play, when Gloria first walked in and was arranging her papers and moving her bag but there was absolutely no sound whatsoever. As an audience member, it really felt as though you were looking in on their interview from the other side of the two-way mirror.
It must be said that you simply cannot switch off or even onto standby for a moment. Building The Wall demands your full attention and keeps you listening right until the end. It is a thought-provoking and exciting production. I would recommend it to anyone with an interest in modern politics or American drama. Perfect for young adults aged 13+.
