Stephen Mangan

Eco-warriors are ripe for satire, and this zany mockumentary makes a decent fist of sending them up. Stephen Mangan and Rhys Thomas play two friends who want to help to save the world by becoming the first carbon-neutral, organic vegetarians to reach the Pole. It's funny in places but lacks direction.

In a comedy based on Douglas Adams's novels, Stephen Mangan stars as detective Dirk Gently, whose investigative technique is based on "an unswerving belief in the fundamental interconnectedness of all things". Happily, the switchback script here, by Howard Overman (Misfits), has a kind of pointedly whimsical quality that's pure Adams. Although there are moments when Mangan's energy overwhelms the rest of the cast, you suspect Gently's creator would approve.

Meddling with the novels of such a geek luminary as Douglas Adams is a precarious business, so it's no surprise that this reworking of his Dirk Gently's Holistic Detective Agency - first shown on BBC4 last December - had ardent fans up in arms over the deviation from its source novel. But a series has been commissioned, so all their favourite bits of the books have a chance to make it to the screen. For the rest of us there is enough to appreciate in a plot that expands from a case of a missing cat to some surreal flights of fancy. Stephen Mangan is great as the chaotic, evasive Gently, while Darren Boyd does a great line in bewilderment as an unwitting sidekick.

Stephen Mangan's not-great-but-better-than-expected turn as Douglas Adams's holistic detective actually stands up to a second viewing, so even if you watched it on BBC4, you may be surprised to find you like it more this time around.

Fans of Douglas Adams were unimpressed with this reworking of his Dirk Gently's Holistic Detective Agency when it aired on BBC Four last year - they felt it deviated too far from Adams's original novel. Tonight, it gets its first terrestrial airing with the detective (Stephen Mangan) examining a case that links a missing cat with an exploding warehouse.

The latest sitcom from Friends co-creator David Crane stars Stephen Mangan and Tamsin Greig as a British couple who write a hit BBC TV show. They move to LA to recreate their sitcom for a US audience, but realise the studio execs have no intention of sticking to their original concept. Enter the great Matt LeBlanc (Friends' Joey), playing a caricature of himself, who is horribly miscast as the show's protagonist, much to Mangan and Greig's vexation. Frequent laugh-out-loud moments and a host of endearingly awful characters make this series feel like a very promising start, but Americanised one-liners fail to capitalise on Mangan and Greig's distinctly British delivery.

Episodes staring Stephen Mangan and Tamsin Greig (both from Green Wing) tells the story of two of successful British comedy writers trying to translate their award winning show to an American audience. Various US TV executives plug in to the process with their ideas of what the public want and how to Americanis(z)e the show, which includes the casting of Friends favourite Matt LeBlanc in the original role. The idea, on paper, is sensational but it's a shame this doesn't quite transfer into practice.

While it was engaging enough to stay tuned until the end, the laughs were few and far between. The concept was in the Gervais-Merchant-esque mould: a form of 'reality comedy' which does cause derision amongst the UK comedy hierarchy - Lee Mack for one isn't a fan - but this one was just a bit wanting in all areas.

The show has been left dangling, hinting at another series, on an interesting cliff hanger, however at this stage it's hard to tell where exactly a second series could go. For my money, the major funny areas of conversion have been covered. While it was an interesting experiment, in the end the true test of comedy is always laughter, and I'm sad to say Episodes lacked a good shot of that.

Last year the BBC aired Grandma's House, Simon Amstell's acerbic sitcom about a dysfunctional Jewish family. The very mixed notices it received have clearly not deterred Channel 4, who keep the middle-class Jewish mayhem coming with this new series from writer Robert Popper. Each episode centres on Friday night dinner with the Goodman family. Bickering brothers Adam (Simon Bird, star of The Inbetweeners) and Jonny (newcomer Tom Rosenthal, son of sports broadcaster Jim) are reluctant attendees, while their mother Jackie (Tamsin Greig, fresh from appearing alongside Matt LeBlanc and Stephen Mangan in Episodes) and father Martin (Pulling's Paul Ritter) try to uphold some family values. In tonight's opening episode, Jackie is intent on getting the boys to watch the MasterChef final, while Martin is preoccupied with rescuing old copies of New Scientist from the dump. Things are further complicated by the continual interruptions from weird neighbour Jim (Mark Heap), who claims to have broken his loo. As a comedy, it's not mean-spirited and cynical, but actually rather sweet. Of course, It's too early to say if it'll be a hit - in particular it is unclear whether Bird has acting gears other than his sarcastic, awkward Inbetweeners persona - but there's certainly enough here to keep you watching.

If you saw the opening episode six weeks ago you can skip the first 10 minutes tonight, which is a scene-for-scene retread. Things improve thereafter, as scriptwriter Bev's (Tasmin Greig) quest to escape the hell of Tinseltown and her feckless partner Sean (Stephen Mangan) leads to a clearing of the air between her and the star of their programme, Matt LeBlanc. The two have previously disagreed; he thinks she is prissy and uptight, she thinks he is a boorish lout. Both actors seem to be naturally suited to their roles, and their reconciliation is one of the better 20 minutes in an underperforming series.
