A few years ago something curious happened to Tom Hollander. He grew up. As a brilliant young actor he won the Sunday Times Ian Charleson Award for a series of stage performances whose governing tone was mercurial energy. But as he moved into film, the sense was of an actor who was more eager to be noticed than believed. In the past few years, however, he has found a vulnerable side, as a hapless government minister in In The Loop and most recently as a minister of the church, the Reverend Adam Smallbone. This week sees Rev’s second coming.

Actors who migrate between stage and screen are often asked in interviews to assess the different disciplines. The answers tend not to vary much. On stage, they explain, you have to make a gift of your performance. In front of the camera, that invasive piece of equipment, you have to be selfish, to hoard, and maybe send out depth-charged truths in the form of discreet flinches and flickers. That’s what’s meant to happen anyway.

At Murry Bergtraum high school in Queens, New York, John Leguizamo was voted the "Most Talkative" student by his classmates. Not much has changed. As this one-man show demonstrates, Leguizamo talks like a Gatling gun on speed, switching almost unconsciously between English and Spanish, and likes to rattle through a gallery of impersonations with scurrilous, hyped-up intensity.

Since breaking onto the movie scene in 2001 with major roles in A Knight's Tale and A Beautiful Mind, London-born Paul Bettany (b 1971) has pretty much gone through the card.

To celebrate theartsdesk's second birthday on Friday, we held a panel discussion on The Art of Performance at Kings Place, London, in the Kings Place Festival.

On 9 September theartsdesk, Britain's first professional arts journalism site, will be two years old. To celebrate we’re holding a live debate with four leading performers during the Kings Place Festival. An actor, a singer, a dancer and an instrumentalist will share their different experiences of performance. Join us, live or online, for a stellar event.

Having masterminded the existential fantasy of Lost, reinvented Star Trek and served up the monster-on-the-loose rampage of Cloverfield, JJ Abrams now comes trampling all over Steven Spielberg's favourite turf of a homely, nostalgic America. He can feel Spielberg's benign hand resting on his shoulder though, since the Big 'Berg co-produced and brought aboard several of his favourite sound and visual effects specialists.

Whatever the quality of the material with which they're grappling, there are two undeniable truths about the Belarusian actors who've put their already curtailed freedom on the line by coming to the Almeida Festival this week: they're skilled practitioners of their art and courageous human beings. Read their biographies in the programme and you'll see that the words "detained", "arrested", "attacked", "dismissed" crop up rather a lot. In Europe's last dictatorship, stepping out on stage and speaking a line, a word even, can lead to imprisonment.

Shared Experience is certainly living up to its name; in a radical departure from normal theatre conventions, the company is currently sharing part of its rehearsal process with audiences as it develops Helen Edmundson’s latest work, Mary Shelley, which tells the astonishing story of how Shelley came to write Frankenstein at the age of only 18.

When the Royal Shakespeare Company seemed to be falling apart in the late 1990s, there was genuine cause for concern. The troupe had no automatic monopoly over performances of Shakespeare, nor could it claim a very particular style in its stagings. But since the 1960s it had held a special place at the higher end of British theatre culture as the natural, and national, promoter and evolver of the world’s greatest body of plays. By 2001, under artistic director Adrian Noble, the RSC was out of London, in retreat in Stratford-upon-Avon, and looking punctured. It was an unhappy sight.
