It’s not often that a venue’s stage door is easier to find than its main entrance, but The Old Vic Tunnels is one such location. For those behind Coming Up Later, however, this is all part of the fun of a three-evening underground festival featuring a rather wonderfully haphazard range of performances. The event is the product of The Old Vic’s outreach programme, Old Vic New Voices, and the funding and artistic crowd-sourcing network IdeasTap.com. Such collaboration resulted in an opportunity few emergent creative directors could ignore: a production team, a budget to play with and three expansive tunnels for those who could imagine how best to use them.

It's the hard-hitting hoedown of high summer. Old Vic supremo Kevin Spacey being reunited with director Sam Mendes for the first time since 1999's American Beauty was bound to make 'em whoop, and their new production of Richard III doesn't disappoint. It's big, bellicose and full of braggadocio, as it should be: the play works best as a series of melodramatic blasts - Gloucester's opening soliloquy, his wooing of Lady Anne, Queen Margaret's curses, Gloucester's mock reluctance at becoming king, his nightmare and defeat as King Richard at Bosworth.

Sexual intercourse, according to Larkin, began in 1963. By 1974 it had had a free-thinking, free-loving decade to become comfortable and frankly rather routine. It was the year the Ramones formed, when The Texas Chainsaw Massacre was in cinemas and Erica Jong’s Fear of Flying on bookshelves. Over at the Royal Court the “angry young men” might still be angry, but weren’t exactly young any more. The sexual revolution had been fought and won, and the cultural battlefield was now overgrown with a riotous tangle of attitudes and influences, each more liberal than the last.

I can tell you the year (1983). I can tell you the theatre (the newly opened Barbican), the actors (Gambon, Sher), and the speech (“Blow, winds, and crack your cheeks!”). Hell, I can all but tell you the seat number. Lear and the Fool in the storm stood on a platform mounted on a high pole. It was an arresting way of establishing their elemental isolation. Or it would have been if the gantry gaining the actors access to the platform had been withdrawn. “That’s not meant to be there,” said the person next door to me. And then louder, “They’ve got it wrong.” My father.

Most critics have their own indicator of shows they have enjoyed hugely; for my part, if I fail to take anything but the most basic notes it’s because I’m so engrossed in the story or I’m laughing too much. And so it proved last night, when I found only hastily scribbled words - great this, wonderful that - in my notebook, enough to tell me that Richard Eyre's production of Georges Feydeau's 1907 farce A Flea in Her Ear is a hoot.

Derek Jacobi (b 1938) grew up in Leytonstone. His father was a tobacconist, his mother worked in a department store. Although he entered the profession in the great age of social mobility in the early 1960s, no one could have predicted that he would go on to play so many English kings - Edward II, a couple of Henry VIIIs and Shakespeare’s two Richards - as well as a Spanish one in Don Carlos. This month he prepares to play another king of Albion: Lear, against which all classical actors past a certain age must finally measure themselves.

Design For Living is one of Noël Coward’s less performed plays but it fair crackles with bons mots - you know you’re in good hands when delightfully old-fashioned words like “horrid”, “bloody”, “cheap” and “vulgar” are tossed around with, well, gay abandon. What a shame, then, that Anthony Page’s production, while wonderfully easy on the eye and despite some spirited performances from its three leads, doesn’t quite catch fire.

There is no consensus about what site-specific theatre actually constitutes. Does it grow organically out of the space in which the theatre piece is performed, and can therefore be staged nowhere else? Or is it no more than any theatre piece which happens away from the constricting formality of the thrust stage or the proscenium arch?

The second season of the Bridge Project - a transatlantic relationship forged between between Kevin Spacey, artistic director at the Old Vic in London, theatre and film director Sam Mendes, and Joseph Melillo, executive producer of the Brooklyn Academy of Music - which aims to make theatrical connections in a series of cross-cast co-productions with American and British actors, has opened with a double header of Shakespeare. At first sight, As You Like It and The Tempest may not appear obvious bedfellows but, as Mendes (who directs both plays) points out in his programmes notes, they both feature a bloody sibling rivalry and a touching father-daughter relationship, and he subtly underlines those parallels.
