Forget round tables, shining swords or even knights who say "Ni!" This muddy promenade production is, in Hollywood parlance, Arthur: Before the Legend.
As there are no generally agreed facts about Arthur, writer Keith Dewhurst gives us his own version of his rise to power. In the late fifth century, Artorius, a Romano-Briton, is besieged by barbarian hordes. His supporters are unconvinced about this new-fangled "Britain" they're supposed to be defending.
Unfortunately, Dewhurst has created a slate of dull characters and tiresome anachronisms. Guenhumara - Guinevere to be (Shelley Islam, better than most) - has a nasty mobile phone habit. In a particularly ill-judged lurch towards the surreal, the poet Tennyson potters on to talk about the construction of Arthurian legend.
At first, directors John Terry and Mike Bartlett make their promenade concept exciting, as the busy actors bustle among the audience. Yet the confines of the space soon become apparent. Promenading really is best when there are lots of square metres to play with. As for the largely static second half, be quick to bag one of the few seats.
Or perhaps stay at home with The Lady of Shalott.
Until 9 December (020 7503 1646).
