Peter Serafinowicz

As befits a sketch show that made its debut online, this takes aim at the internet and gaming culture, beginning with a Facebook morality tale that's as likely to make you wince as guffaw. Appropriately, the comics include YouTube stars Chris Kendall and Jenny Bede, who made a name for herself after spoofing Cheryl Cole, while Peter Serafinowicz supplies a deadpan voiceover. Highlights include a Sherlock sketch in which the investigator's ability to see clues everywhere proves more hindrance than help, and a prime minister who can't tear himself away from his laptop.

Mangling accents and genres with glee, Bad Sugar is one of the more promising pilots of C4's Funny Fortnight. Starring three-headed comedy hydra Julia Davis, Sharon Horgan and Olivia Colman, it's equal parts telenovela, costume drama and pseudo-glossy, 'Dallas'-style family saga. The plotting - centred around the will of an ageing patriarch (David Bradley) and the scheming of his three children (plus Horgan's cuckoo in the nest, Lucy) - is self-consciously ridiculous. But Bad Sugar is sustained by a host of brilliant performances. In addition to the above, look out for Kayvan Novak (dim gardener Simon) and Peter Serafinowicz (closeted son Rolf). Tonight, the fingers of Colman's piano-playing naif Joan are mangled by a red-hot boule ball; the absurdity can only escalate when a full series airs next year.

Amnesty brings its comedy fundraiser to the US for the first time to celebrate the organisation's 50th birthday. The line-up is an Atlantic-straddling bobby dazzler at New York's Radio City Music Hall: the US contingent includes Jon Stewart, Sarah Silverman and Kristen Wiig, and the UK sends Peter Serafinowicz, Noel Fielding and Russell Brand. Music comes from Coldplay and Mumford & Sons. The ball always comes off best when it's a combination of standup and sketch comedy, so fingers crossed for some surprise team-ups.

Before I start I should point out that I've never really been a huge fan of Lenny Henry, but I must admit that The One Lenny Henry wasn't as bad as I thought it was going to be. For me his stand-up was better than his sketches, particularly the material about film piracy and trying not to be funny when performing Othello.

However, most of the sketches were a bit dull, lacklustre in places and in several cases thought he was overshadowed by those alongside him; in particular Peter Serafinowicz and Omid Djalili.

On a final note, during the show Henry gave a short rant about obituaries, saying that when he dies his will probably read "Premier Inn Bloke Dies." I'd just like to say: "Whose fault is that exactly, Lenny?"

Remember when they gave Ronnie Corbett his own show last Christmas and called it The One Ronnie? The idea is the same here, as we start a trio of shows involving veteran comics (Griff Rhys Jones and Jasper Carrott follow) who revive old characters and link up with guest stars. Lenny Henry has more old characters than most, and revives memories of sex-obsessed old gent Donovan Bogarde and "cru-shall" Brixton DJ Delbert Wilkins, now coming at us via YouTube.

The best sketch is a showcase for Peter Serafinowicz, playing a white bloke who can't stop talking in black patois, and there are decent spoofs of Twilight and Cee Lo Green videos.

Was the BBC's 2010 Ronnie Corbett-centric Christmas special The One Ronnie really so successful that they feel able to riff on the title for this similarly outdated Lenny Henry showcase? The first minute-and-a-half - as Lenny busts into a serious Swedish crime drama - promises good things, but it's downhill all the way from there: there really isn't a single joke here that works. It's partly redeemed by the fact that Lenny remains an effortlessly likeable performer, even in the most cringeworthy sketches - and there's some spectacularly lazy writing here, particularly when it comes to tackling anything political - and by a guest cast including Ronni Ancona and Peter Serafinowicz. A mostly harmless half hour, but don't expect a comeback.

Lenny Henry reminds us he was once a big name in comedy with this one-off show mixing brand new stand-up and sketches while revisiting some of the best remembered characters from The Lenny Henry Show. Supercool Delbert Wilkins, smooth-talking Donovan Bogarde and love god Theophilus P Wildebeeste rub shoulders with guests Ronni Ancona, Omid Djalili and Peter Serafinowicz in spoofs of The Killing, EastEnders and Twilight, among others.

BFI celebrate 10 years of Look Around You

Peter Serafinowicz: A big name in comedy

He's a superb mimic and talented comic actor who pops up in all manner of programmes - although his own star vehicle was short lived. But the prolific Peter Serafinowicz is about to have a bumper year, with a batch of new movie projects in the pipeline.
