There was once a time when grime music was very angry, and very threatening, but that seems a long time ago now. Today, Dizzee Rascal is less a herald of riot and revolt, and more of a national treasure, exuding charm from every pore, even if his music has become increasing predictable and safe. But, as wordsmith and dancer Debris Stevenson proves in her debut play, Poet in da Corner, Dizzee Rascal still can change minds and influence people.

Why is M.I.A. such a problematic pop star? Why can't she just shut up and release a hit? Tellingly, this is the very question the singer poses at the start of Matangi/Maya/M.I.A - a question she's been asked throughout her career, from interviewers to management.

As the Syrian conflict enters its final convulsions, renewing memories of how the Sykes-Picot agreement – between an Englishman and a Frenchman – would cause more than a century of political resentment in the Arab world, The Outsider seems particularly piquant.

When director Jenny Lu graduated from university, the promise of a big city career quickly turned into a series of rejections. Around this time, a close friend of hers committed suicide by jumping off a bridge – unbeknownst to their circle of friends, this girl was working in the sex industry.

Les Dennis was once a marquee name on Saturday night television as host of Family Fortunes, but since giving up the light entertainment lark he now plies his trade as an actor, and a very good one at that. If you've not seen it, give yourself a treat and watch his bang-on-the-nose performance as “Les Dennis”, a delusional, whinging has-been, in Ricky Gervais and Stephen Merchant's Extras.
