What sort of physical upgrade can a play withstand? That question will have occurred to devotees of Brian Friel's Translations, a play that has thrived in smaller venues (London's Hampstead and Donmar, over time) and had trouble in larger spaces: a 1995 Broadway revival, starring Brian Dennehy, did a quick fade.

The idea of producing a classic play in a mix of two languages is pretty odd. What kind of audience is a bilingual version of Molière’s best-known comedy aiming at, you wonder. Homesick émigrés? British francophiles with rusty A-level French? Neither constituency is likely to be satisfied by this curious dish that is neither fish nor fowl.

Question: is Consent, transferred from the National to the West End, a sharp-tongued comedy or an acute reinvention of a revenge drama? There are more than enough smartly placed laughs throughout the tart, increasingly taut first act, to make you think you’re watching an amusingly balanced, if increasingly vicious, exposé of the divide between the private and professional lives of lawyers.

I’ve forgotten my wallet.

This exuberant production both clarifies and further complicates the conundrum of Peter Pan. In any production true to Barrie there is an underpinning of sadness, an acknowledgement of the losses we must all suffer: children leave home and adult responsibility takes the place of childhood innocence.

Add Catalan writer Jordi Galcerán to the shortlist of European playwrights who are finding an international perch, in this case with a tricksy four-character play that has had more than 200 productions in over 60 countries.

Calixto Bieito has a reputation as a radical theatre-maker, and by any standards The String Quartet’s Guide to Sex and Anxiety is an unusual, genre-breaking piece; Bieito has described it as “like a symphonic poem for a quartet of musicians, and a quartet of voices”.

There’s a distinct feeling of back to basics to this opening double bill at the Globe under the theatre’s new Artistic Director Michelle Terry. The elaborations (some would say gimmickry) of Emma Rice’s short tenure have been reined back, and a new concentration prevails.

The show’s subtitle – “Songs banned by the Nazis” – is a catchy one, and somewhere under the confetti, the stilettos, the extravagant nudity, the sequins and even shinier repartee that are wrapped around Effigies of Wickedness like a mink coat on the shoulders of an SS officer’s mistress is the bruised and grubby story of one of history’s foulest episodes.

Towards the end of the Maly Drama Theatre of St Petersburg's Life and Fate, a long scene in director Lev Dodin's daring if necessarily selective adaptation of Vasily Grossman's epic novel brings many of the actors together after a sequence of painful monologues and one-to-ones.
