If the announcement of new plays was measured according to the Richter scale, it's safe to say the news Sir Tom Stoppard has written a new drama — Leopoldstadt, premiering in London's West End next year — would rank as top-end seismic activity.
It's all the more startling for the fact that some of us had impertinently concluded that the man often hailed as Britain's greatest living playwright was in his dotage, winding down (he's 81).
Stoppard has brought rigour to the business of theatre-going, writing work of commercial viability that has challenged audiences to explore demanding subject areas, galvanising a sense of what is possible in the art form.
His impulse to think big can be detected in the courageousness of younger playwrights such as Rupert Goold, Nick Payne and Lucy Prebble. His brain-boxiness was there at the start in 1966 with his name-making, absurdist spin on Hamlet, Rosencrantz and Guildenstern Are Dead.
He put a pyramid of acrobats and a moral philosopher with an unfashionable faith in God centre-stage in Jumpers (1972), performed intellectual gymnastics with Joyce, Lenin, and dada founder Tristan Tzara in World War I Zurich in Travesties (1974) and reached a peak of knowledge-crammed ingenuity with Arcadia (1993), which shuttled between centuries interweaving thoughts on Newtonian physics, chaos theory and more.
