In I’m Gonna Pray for You So Hard, Halley Feiffer has written a right curmudgeon of a central role. David is a successful playwright, a Pulitzer Prize-winner who has no difficulty slotting himself directly into the great American drama tradition. He’s also such a testy individual that even being in the same room as him for very long is an endurance.

There's an irony to be found in the fact that America's 45th president is already abolishing any and all things to do with the arts even as his ascendancy looks set to provide catnip to artists to a degree not seen since the heyday of Margaret Thatcher.

Coalitions make for drama, and for comedy. We know that from, respectively, Borgen and the final series of The Thick of It. It is little wonder therefore that soon after the 2010 election delivered a hung Parliament, the National Theatre commissioned a play. And yet the drama that emerged was not about deals struck in back rooms by the Cameron-Clegg government. Instead, This House spirits its audience back to 1974, the year Labour embarked on five years’ of horse-trading as it sought to govern the country with an overall majority of three.

It’s a strange time to be alive. Has it always felt like this? When else was there a time when so much felt to be at stake, and the ground moved beneath our feet with the continuous emergence of technologies that affect our everyday lives and our very being, where we know little of our interior selves and yet publish so much about our lives to strangers? We are the chosen generation, we are the people who will be witness to the most radical change in society the world has ever seen! We are fated and also incredibly special! I am special, I must be!

To begin writing a book is to start something over which you are going to lose control. As it comes to life, a book acquires its own quiddity, its own interior authority, and if the writer does not obey this authority she ruins the book. A Man of Good Hope tells the true story of Asad, a Somali refugee who embarks on an transcontinential journey to reach South Africa. About halfway through the writing, the book began demanding that I stick uncompromisingly to Asad's point of view as he was subjected to South Africa’s relentless, slow-drip violence.

"I've always thought there's nothing worse than coming to the end of your life and realising that you haven't participated in it, and so I write about people who've done that to a certain extent." Edward Albee has died at the age of 88, having participated in his life far more actively than George and Martha, the couple in Who's Afraid of Virginia Woolf? whose idea of hell is each other.

In the opening scene of Boys Will Be Boys, the lead character, Astrid, talks about how there’s a boys’ world and a girls’ world. Boys’ world is where you want to be. That’s where power is, that’s where fun is. Boys get to be boys and that means holding all the cards, and doing whatever the fuck you want. How do women get into boys’ world when they’ve got a vagina?

It’s a little over two years since I was approached to adapt The Mighty Walzer by Howard Jacobson for Manchester Royal Exchange. I was living in Liverpool at the time and had recently seen That Day We Sang by Victoria Wood at the Exchange. It was terrific, wonderfully directed by Sarah Frankcom. I had never seen a musical in the round before, it was so dynamic. There’s nowhere to hide in the round, you can’t get away with anything, you’re totally exposed, and I remember thinking how great it would be to write for such a space.

Nothing quite prepares you for your first sight of Thiepval, the Memorial to the Missing of the Somme. I had read about the events it commemorated and, before that, been told about them as a young boy. I’d studied the war poets at school and as a teenager had been introduced to Robert Graves’s Goodbye to All That and Erich Maria Remarque’s All Quiet on the Western Front. I knew about the vast numbers of war dead, of how they exceeded the populations of famous cities.

It’s either serious or it’s funny. That’s a view I quite often encountered when working in Germany. A theatre professional there once advised me to remove all references to writing television comedy from my biography in the theatre programme.

“Why?” I asked.

“People will think you’re not a serious playwright.”

“A serious playwright can’t write comedy?”

“It’s a bit worse than that.”

“How, exactly?”

“Well, it’s not just that you’re writing comedy, it’s that you’re writing comedy for television.”

“Is that bad?”

“It’s not good.”
