Blocking a Thrust with a Sightline Problem
A school is performing a 40-minute excerpt from a Greek tragedy on a temporary thrust stage built into the front of the auditorium. The thrust is 6 m wide and projects 4 m into the audience, with seating on three sides. The director has blocked the chorus of nine students in a straight line across the back of the thrust, facing the audience in the main seating bank. At the first run-through, the drama teacher observes that audience members seated at the two side banks can see only the chorus members nearest them, and that the central actor's key monologue is delivered while she stands directly behind two chorus members. The set consists of two 2.4 m tall columns placed 1.5 m apart at the rear of the thrust. The director insists the straight-line chorus is 'the classical picture' and does not want to change it.
1. Analyse the staging problems created by the thrust and the director's blocking choice, and propose a revised blocking concept that keeps the director's intention while solving the sightline issues.

A thrust is an open staging form: the audience surrounds the action on three sides, so there is no single 'front'. The director's straight-line chorus facing the main bank treats the thrust as if it were a proscenium, which is the root of both problems.
Problem 1 - side-bank sightlines. Nine students in a line across a 6 m width means each side bank sees the chorus in profile or from behind, and the line itself blocks the diagonal views. The 'classical picture' the director wants is a frontal picture that only one bank can see.
Problem 2 - the monologue is masked. The central actor stands behind two chorus members, so the most important text in the excerpt is literally hidden from a large part of the audience. On a thrust, the actor's position must be chosen for all three banks, which usually means placing the speaker forward and downstage of the chorus, not behind it.
Revised concept: keep the chorus as a unified body but change its shape from a line to a wedge or semicircle opening toward the main bank, with the two side wings angled so each side bank sees faces. Place the columns to frame the two rear corners rather than at the centre, so they do not create a narrow slot the actor must speak through. For the monologue, bring the actor downstage centre of the thrust, in front of the chorus, and have the chorus turn inward to watch her - this preserves the classical ensemble picture while giving every bank a clear view of the speaker. Rehearse the monologue from three marked sightline positions (one per bank) so the blocking is tested, not assumed.
2. The director argues that classical staging 'should be seen from the front anyway'. Construct a reasoned response, using the specific dimensions and audience layout of this production.

The claim confuses historical convention with this venue. A Greek amphitheatre did wrap its audience around the orchestra, so 'classical' staging was in fact seen from many angles - the frontal picture is a later, proscenium habit. Even setting history aside, the argument fails on the specifics here.
With a 4 m projection and seating on three sides, roughly a third of the audience is at each side bank. A straight line across the 6 m width means the side banks see the chorus edge-on; the two 2.4 m columns at 1.5 m spacing further narrow the central sightlines, so the monologue is masked for anyone off-axis. The director is therefore asking two-thirds of the paying audience to accept a worse experience so that one bank gets the intended picture.
The response should concede the director's real point - ensemble unity and a strong frontal image matter - and show that these are achievable on a thrust through a wedge or semicircle, inward-facing chorus, and a downstage monologue position. The test is empirical: mark the three sightline positions and run the monologue from each. If the director's blocking fails that test, the intention is not being served by the blocking, and the blocking should change, not the audience.
