Some theatre genres seem indestructible. One of these is the satirical city comedy, for which playwrights dip their pens in poison and spray their venom over the teeming mass of the shallow, the stupid and the successful. When they do this today, they inevitably recall all manner of past plays from Jacobean and Restoration times to Richard Brinsley Sheridan’s The School for Scandal, and beyond. In American Trade, a new play from the immensely talented American playwright Tarell Alvin McCraney, which opened last night, we revisit this familiar territory.

If your heart breaks a continent or more away from home, does it make a noise? Very much so in the scintillating Royal Shakespeare Company/Filter collaboration Silence, the second in a series of three RSC premieres at the Hampstead Theatre. Wedding Filter's interest in the synergy between technology and text with a subset of Shakespeareans who have been wandering the Forest of Arden on and off for the past two years, Silence plunges its expert ensemble into the forest of metal that makes up one aspect of Jon Bausor's set. Will the result be as you like it?

Space is a great subject for theatre. I’m not sure why but it might be something to do with the contrast between the irreducible groundedness of live performance and the imaginary flights of fancy that the audience yearns to take. Whatever the reason, memorable past explorations of this subject, from the Soviet side of the space race, include Robert Lepage’s The Far Side of the Moon and David Greig’s The Cosmonaut’s Last Message to the Woman He Once Loved in the Former Soviet Union. Now Rona Munro, whose new play opened last night, once again boldly goes deep into the history behind the first man in space.

My latest play, Little Eagles, marks the 50th anniversary of cosmonaut Yuri Gagarin’s first orbit around the Earth. Gagarin’s place in history is, quite rightly, assured but little is known about Sergei Korolyov, a brilliant engineer and the chief designer of the Soviet space programme. Koroloyov may not have won the race to put a man on the moon, but he was responsible for a series of extraordinary firsts in the space race, including the first human in space. Little Eagles is his story.

Film-maker and playwright Mike Leigh simply doesn’t do revivals. His method of working - which involves a group of actors improvising characters and situations until a story emerges - runs contrary to any notion of returning to a play after its premiere. So it is quite astonishing to report that, for the first time, Leigh has revisited one of his own plays, Ecstasy, which he originally put on at the Hampstead Theatre in September 1979, and which is now back at the same venue.

Playwright Nina Raine has a gift for evocative play titles. Her 2006 debut was called Rabbit, and her sellout success at the Royal Court last year was Tribes. This time, we seem to be on safari with Tiger Country, but appearances can be deceptive.

The Royal Shakespeare Company celebrates its 50th birthday season with the grand reopening of its transformed Royal Shakespeare Theatre at a cost of £112.8 million. The temporary Courtyard Theatre folds curtains on the sold-out smash hit that is Matilda, awaiting one last flourish in the Olympics Shakespeare Festival next year before its intended demolition. New productions of Macbeth, King Lear and Romeo and Juliet inaugurate the revamped RST, while London operations transfer from the Roundhouse to Hampstead Theatre for the premieres of three new plays. The season is capped with a six-week summer residency in New York. Full season listings below.

Once upon a time there was a free spirit called Tim, who fell in love with olde folk tales and created little shows all about spells and wonders, and peopled them with princes and princesses, farmers and animals. When he was more grown up, he formed a gang with another free spirit and then with a lady known as the Poet Laureate, who came from a cold, snow-covered country in the North. Then the three of them created a bigger show and staged it in a city called Bristol in the West of England several years ago. Then finally they brought this show, which had grown and grown, to the chief city of the kingdom.

Few playwrights have been so successful at moulding our view of a nation as Athol Fugard. It’s impossible to think of South Africa, especially during the apartheid years, without thinking of his Sizwe Bansi is Dead, The Island or Statements after an Arrest under the Immorality Act. Since the end of the old regime in 1994, the moral fuel that powered his plays may have evaporated, but this new work, one of nine premiered by the 78-year-old author in the past 15 years, shows that his feeling for stagecraft and his concern for human dignity remain undiminished.

The last time I saw Oscar Wilde’s biblical tale it was performed by dancer Lindsay Kemp at the Roundhouse in London, back in the 1970s, in a production that was high on dope, incense, strange vocal drawling - and which transported you very quickly to hippie heaven. Choked by clouds of fragrant perfume, weird in its singsong language and thrilling in its strangeness, this seemed like an ideal way of realising the crazy vision of this odd piece. But theatre is not about being faithful to fond memories, it’s about the constant restaging of classic plays, so this new version of Wilde’s 1892 play offers a welcome chance to reassess it.
