Graham Linehan

Graham Linehan's brilliant celebration of all things nerdy reaches its fourth series, and as Moss details to Jen the intricacies of Dungeons & Dragons she realises that she would really like to get another job. Roy is heartbroken after becoming, as Moss describes him, Dumpo, the elephant that got dumped. As ever, Moss gets all the best lines. But Matt Berry shines as the ultra-sexist boss Renham, who admits to a group of feminists that nobody could mistake him for Gok Wan. This may not be sophisticated comedy, but it's still hilarious.

A welcome return for the Bafta-winning sitcom set in a corporation's dingy computer department. This is the start of series four. Many would have wielded the axe after a patchy debut run. The show's stay of execution was largely down to affection for writer/director Graham Linehan - the man behind Father Ted and Black Books, Chris Morris collaborator and recipient of comedy's Ronnie Barker Award last year. His creation is now worthy of those credentials, going from strength to strength. Tonight's opening episode is entitled Jen the Fredo, after the weak Corleone brother in The Godfather, and is crammed with knowing nods to the revered Mafia movie. Desperate to escape IT, Jen (Katherine Parkinson) is made Entertainments Manager by unreconstructed boss Douglas (Matt Berry) - a man given to pronouncements such as, "I like my women how I like my toast. Hot and consumable with butter." Jen's new job means showing braying businessmen a good time - and a theatre trip to The Vagina Monologues isn't quite the ticket. Back in the bunker, geeky Moss (Richard Ayoade) is devising Dungeons & Dragons-style role-play games and heartbroken Roy (Chris O'Dowd) keeps weepily guzzling white wine at his desk. All these plot strands come together ingeniously. Most laughs come from Berry and Ayoade's more cartoonish characters, but Linehan isn't too proud to write in the odd pratfall and it's so well-acted, one scene is genuinely touching, despite its silliness.

I haven't been a fan of The IT Crowd in the past, so either this funny opener to season four has climbed a couple of rungs up the comedy ladder or I was totally wrong.

The four leads all seem to tot­­ally inhabit their characters much more than they did when we last saw them 18 months ago and ­everything about it feels that much more relaxed.

A fifth series has already been commissioned which only makes sense - at only six episodes a piece, it would take four British series to make one full-length series in the US.

And that alone could be another reason why it has taken until now for this show to really bed in enough to regularly provide laughs.

Creator Graham Linehan has said he'll write the next series with a team rather than on his own, which should also keep the quality right up there.

Tonight Jen (Katherine Parkinson) has applied for the job of Entertainments Manager at Reynholm Industries, unaware that the role traditionally involves the messy business of procuring hookers for business clients. Happily, Moss (Richard Ayoade) and Roy (Chris O'Dowd) come to the rescue with some alternative amusements - and a sub-plot involving Roy's freshly broken heart that will have geeks sobbing on to their keyboards like babies.

On a special edition of Charlie Brooker's Screenwipe a couple of years ago, Graham Linehan revealed some of his writing secrets: For instance at the time he was writing an episode of The IT Crowd entirely based around a random thought he'd had: 'Wouldn't it be funny if for some reason Roy was topless in the office?' When the episode eventually aired we got the answer to that age-old question: No, actually it wouldn't be particularly funny. But the same series introduced us to the insane genius of Friendface, the social networking site that's like a diseased face of friendship.

So yes, that was basically an entire paragraph to say that The IT Crowd can be very hit-and-miss. And so it is with the opener to Series 4 (a fifth series has already been commissioned.) Despite everyone advising her against it, Jen's got her heart set on being the new Entertainment Manager at Reynholm Industries, only to find out that taking Douglas' guests to The Vagina Monologues isn't what they had in mind. There's some slow patches in the episode but some big laughs as well, like Roy's mementoes of a doomed love affair, and how Jen deals with some horny businessmen who fancy a bit of role-play. And with upcoming weeks promising Moss on Countdown and a geek throwdown, the new series should be worth turning off and on again.

Graham Linehan on writing sketch 'runners'

I was asked recently to turn a sketch I had written into a 'runner' (a sketch that returns weekly featuring the same characters / situation / catchphrase). I didn't think the idea had legs, so I said no, but I have other, more complicated reasons that I've been thinking about for a while now, and I thought maybe I should set them down in case anyone finds them useful.
