Edinburgh Festival 2026

Supposing:

07/08/26

Traverse Theatre, Edinburgh

TravFest starts off strong this year with Zinnie Harris’s magical-realist new play, Supposing:, a blend of mythology, contemporary politics and overt theatricality.

Sally (Nicole Cooper) has fallen down a hole. In literal terms, it’s just a small crater in a road outside a theatre, and she’s not seriously hurt. Metaphorically, however, it’s so much more, not least a portal for a Greek chorus, who promptly take up residence inside her head. Awkward. As if that weren’t enough, she’s also been cursed with the ability to see some very specific aspects of the future…

Sally’s husband, Rich (Richard Conlon), doesn’t believe in her newfound prophesying skills. He thinks she’s suffering from depression – again – or maybe it’s the menopause? Either way, he has absolutely no intention of popping next door to warn their racist neighbour that she has an undiagnosed medical condition, however urgently Sally insists.

It’s not just their marriage that’s under strain. The outside world is a pressure-pot too. The town’s hotels are being used to house immigrants and there are right-wing protesters gathering outside. Sally’s internal chorus never lets up its refrain: Trump, Reform, the climate crisis. Madness seems like a legitimate response.

Cooper’s performance is impressive, at first clipped and precise, then – as Sally plummets ever-deeper down the rabbit-hole – excessive, even flamboyant. Conlon provides an excellent foil, a study in baffled defensiveness and disappointment. Deftly directed by Harris, Supposing: is a timely exploration of our post-truth society, albeit one that poses more questions than it answers about how to navigate the shifting sands.

If this sounds like your kind of thing, don’t hesitate to buy your tickets. You don’t have to be Cassandra to see that this well-crafted, thought-provoking production is sure to be a hit.
