Playing a prostitute on film has been big career business for some very famous actresses, not least Jane Fonda, Elizabeth Taylor and Julia Roberts, but it hasn't worked quite the same way on TV. Unless you count Secret Diary of a Call Girl. Or Moll Flanders. Or The Devil's Whore. Though maybe not Five's brothel sitcom, Respectable.

“Love is no solution to life,” declares a line from Clifford Odets’s 1938 drama; and in straitened times, then and now, it’s a sentiment that carries considerable doleful weight. And yet every character here is in desperate search of that elusive something to elevate the banal business of day-to-day existence – a personal rocket to the moon. Without it, they are trapped in endless Monday mornings, soul-destroying work that doesn’t bring in enough to pay the bills, and relationships in which they turn into “two machines, counting up the petty cash”.

UPDATE 2015: Four years ago, in January 2011, I wrote this article about the music critic and biographer Michael Kennedy's search for the missing portion of Elgar's life. It identified a Mrs Dora Nelson as the composer's mistress and mother of a lovechild, who might have influenced some legendarily enigmatic aspects of Elgar's compositional output. A new development opened when an Arts Desk reader contacted me, who had taken up Kennedy's and my requests for others to pick up this unsolved mystery.

Canadian writer Mordecai Richler’s eclectic contribution to film includes uncredited work on Room at the Top, the screenplay for Fun with Dick and Jane and the original book behind Richard Dreyfuss’s early success The Apprenticeship of Duddy Kravitz. Like that 1959 novel, his final tome, Barney’s Version, dealt with the colourful history of a Montreal Jew.

Adultery has had a good press recently. Websites such as meet-to-cheat.com, illicitencounters.com and lovinglinks.co.uk have been in the news, and statistics suggest that more of us are being unfaithful than ever before. But although adultery is a staple of farce and mainstream drama, there are few plays that deal with the subject with quite the unsettling ambiguity and disturbing depth that characterise Martin Crimp’s modernistic play, first performed in 2000 and now beautifully revived by the up-and-coming Amelia Nicholson.

Middle-class family angst is this season’s theme at the Royal Court Theatre. And, in his new play about sex and intimacy, which opened last night, playwright Nick Payne puts the lust in Wanderlust and creates a contemporary tale of wandering hands and wandering affections. We are in a nice suburban part of England, and the mix of pain and pleasure will be all too familiar to most audiences, whether they are teenagers who can squirm at the antics of the youngsters, or middle-aged couples who might find the more mature characters shockingly recognisable.

Apart from a few nips and tucks, age has not withered Bouquet of Barbed Wire. Anyone who can remember the original steamy adaptation of Andrea Newman’s fine novel will recognise the changes. Prue, no longer the manipulative cow who graced our screens back in 1976, has been made-over as an unworldly innocent, while husband Gavin – still a deeply unpleasant wife-beater - is now a chippy, working-class Yorkshireman rather than a chippy American. And Peter, the daughter-obsessed patriarch, appears to be an altogether more anguished soul - though one suspects this has more to do with Trevor Eve’s ability to play complex, nuanced characters far better than the stiff, granite-faced Frank Finlay.

This award-winning series, created by Tom Kapinos in 2007, is groundbreaking television even by Showtime’s daring standards. Californication is a dark - very dark - comedy drama about Hank Moody (David Duchovny), a bad-boy writer who has lost his literary mojo, but absolutely not his mojo mojo, as it were; it has nudity a-gogo, frequent sex scenes, recreational drug-taking and frank discussion of sexual matters.

Usually a seasonal home for the pastel-coloured delights of drawing-room farce, musical comedy and the odd Shakespeare pastoral, Regent’s Park Open Air Theatre is this year offering a programme of rather darker hue. With Macbeth to follow later in the season (not to mention Stephen Sondheim’s deliciously off-white fairytale musical Into the Woods) it was with a new production of Arthur Miller’s The Crucible that things kicked off last night.
