Oslo

'A serious, and seriously good, play… when the interval came, I felt deprived, like you do when you are reading a great book and have to put it down even though all you want to do is to go on reading'

'An extraordinary achievement, hands down the best new play of the season. Creating riveting drama out of the intransigence of implacable enemies is no modest trick, but darned if J.T. Rogers doesn't pull it off, and grandly... a dramatist of generous spirit writing with persuasive compassion about his characters'

'A tremendous piece of theatre… witty, gripping, Shakespearean in scope… what is most heartening about it is the way it quietly celebrates the peacemakers and their resolute belief in a common humanity. At a moment when acts of violence are never long out of the news, this is timely and immensely moving'

'A deft combination of research, fictional intuition and dramatic compression… watch, learn and marvel'

'This weighty subject, full of labyrinthine complexity, is lucidly distilled by JT Rogers's dramatisation of events, turning the process of negotiation and diplomacy into a gripping drama … it is a rollercoaster, with moments of great hilarity switching suddenly to high tension, along with deeply moving reminders of the horrors and sadness behind the talks'

'A proper political thriller… Rogers [has] a real eye for the human side of history... keeps the tension dead taut throughout'

'Rogers' scrupulously researched work has a remarkable lightness of touch. It's witty, nimble and full of pleasing detail… works both as a piece of documentary theatre, unpacking a historical moment, and – in a time of what feels like increasing social division – a valuable reminder of just what can be achieved if people are wiling to put aside their own agendas and work towards a common good'

'Unequivocally fascinating... Rogers' clever dialogue is very witty. You get the facts, but you get them delivered with intelligence and humor'

'As expansive and ambitious a play as any in recent Broadway history... [has an] urgent behind-the-scenes intimacy at its fast-beating heart... [Rogers' script] is a marvel of both expository efficiency and exciting showmanship, by which a big picture is revealed to be a composite shot of precisely defined, imperfect individuals. Oslo features a vast cast of characters, of widely varied temperaments and ideological stripes. Yet somehow, by the end, you feel you have come to know every single one of them'

'Bracing and absorbing... the balance of passion, discipline, and suspense is organically, thrillingly theatrical'
