It's 30 years since Stephen Sinclair co-wrote the hit play Ladies Night and, in the ensuing years, he's kept busy with a range of film and theatre writing projects including Lord of the Rings: The Two Towers.
His latest play shows how varied his interests are. Whereas Ladies Night was a comedy about a group of unemployed workers who devise a male strip show, Remain in Light is a post-apocalyptic tale about what happens when the sun fails to rise.
It starts with frightened groups of humans foraging for food and doing their utmost to survive in endless darkness. When one man finds a magical source of light, the power and the control he can exert on others becomes limitless.
Relevant themes for a world facing political and environmental turmoil? That's partly true, says Sinclair, but he was equally fascinated by the technical challenges and possibilities of working with low light.
That interest started in 2013 when he wrote a play called Intimacies and was watching actors Rima Te Wiata, Lynn Waldegrave and Ross Brannigan rehearse on a darkened stage. Sinclair got curious about what would happen if we were plunged into eternal night.
"I'll start thinking about something and, once the idea takes hold, it usually doesn't go," he says, adding that themes of power and rapid technological change seem to be "asserting themselves" in his present writing.
It won't be pitch black in the theatre, but it may be darker than other stage shows and he's interested in the ways in which imagination fills in the gaps. Sinclair is quick to say the show's not bleak, but more about freedom and redemption.
With a 17-strong cast, directed by regular collaborator Elena Stejko, he says it's exciting to work on a project where more people on stage also adds to the atmosphere.
"You can get some amazing dynamics going on with that many people."
Between the comedy of Ladies Night, written with Anthony McCarten, and the sci-fi darkness of Remain in Light, there isn't much Sinclair hasn't tackled: historical dramas, adult comedy, surrealist fantasy; they're all on his CV along with poetry, a children's story and a novel.
While Sinclair's been working on Remains in Light, he's also been researching for his next project. It's an historical novel set in Britain where, from the late 4th century, Roman rulers came under increasing pressure from barbarian insurgents.
He hopes to travel to Britain later this year to complete the research.
