Religious mania is bad for your love life. In Enda Walsh’s revamped 1999 play — which has already been seen in Galway and New York, and opened in London last night — a 33-year-old man (played with immense conviction and enormous presence by Cillian Murphy) invites us inside his mind to explore the dark and dangerous caverns of religious enthusiasm and psychological collapse. Be warned: it is a strange, tormented and rather weird trip.

Seeing Miss Julie played in-the-round would, I suspect, have delighted Strindberg. In his preface to the play, he was much exercised about the setting, presuming a proscenium stage: a single set, asymmetrical scenery, no clutter, no “tiresome” exits through doors, no footlights. And so on.

It’s the star factor. Tickets for Big and Small, by the controversial German writer Botho Strauss, are selling fast because Cate Blanchett is in it. Her protean presence in this production by the Sydney Theatre Company, of which she is the co-artistic director, casts a glow over the whole event — she’s on stage for almost the entire running time of two and three-quarter hours. But there are other pleasures to savour here: chief of these is playwright Martin Crimp’s fresh, crisp and contemporary translation of the text.

When Madani Younis became the new artistic director of the Bush, some questioned his commitment to new writing, while others asked what he would bring to this small but high-profile venue. With this, his inaugural production, which opened last night, some answers suggest themselves: he’s chosen a solid new play, and he has introduced London audiences to a Lee Mattinson, a northern voice.

We’ve seen a few American film and TV actresses grace the West End stage with surprising potency, but no one surely will surpass Laurie Metcalf for profound emotional truth-telling in Eugene O’Neill’s shattering family drama, given an unbeatably cast new production in London’s West End. Metcalf's by no means famous over here now, so long after her brilliant stint in Roseanne Barr's Nineties sitcom, but this is one of those performances you won't forget, up there in the Vanessa Redgrave class.

The cultural triumvirate of the Hallé Orchestra, the Royal Exchange Theatre and The Lowry have joined forces for this new production of the 1953 hit musical Wonderful Town. Leonard Bernstein would surely have been a happy man to hear his score, dashed off in a mere five weeks at short notice, played by the 65-strong Hallé Orchestra conducted by Sir Mark Elder, who has been nursing the ambition to do the show here since he saw the 2004 Broadway production.  

Fisher has pizzazz and a gift for comedy

The world premiere here of Monkee Business the Musical was planned long before the untimely death in February of Davy Jones, the Manchester-born member of the manufactured band that outsold The Beatles and the Rolling Stones half a century ago. The coincidence lends a poignancy to the event and the Manchester run has been dedicated to his memory.

A play of boundaries, limitations, barriers, one that gazes outwards while never crossing the threshold, Uncle Vanya is often betrayed by the physical space of major stagings. In a new production at Notting Hill’s The Print Room the audience find themselves trapped along with Vanya, Sonya and their dysfunctional family in a single room. Ranged around the four walls we crowd in upon the (in)action, waiting together with the characters for the rupture that will release the tension.

This is the Jacobean tragedy that probably gave Quentin Tarantino his best ideas - by the end of the night the body count is almost in double figures through stabbings and strangulations. But even as the fake blood flows and the gurglings mount, Jamie Lloyd's sturdy but sometimes sluggish production of John Webster's masterpiece (c 1614) isn't exactly gripping.

Little more than a year since The King’s Speech hit pay dirt at the Oscars, David Seidler’s tale of a prince stuttering between duty and impediment takes to the stage. Rather than a speedy and cynical exploitation of the film’s success, the move actually reflects Seidler’s original ambition for his story; and while we might reasonably have feared déjà vu and a pale shadow of the film, what we discover is a thematically richer, yet equally delightful experience.
