The Nightly Show with Dermot O'Leary review

Likeable host turns on charm to salvage ITV's broken format.

Viewers slam 'boring' Dermot O'Leary

He didn't have The X Factor during his first show as host.

Radio Times review

If you've been missing Dermot O'Leary since he left The X Factor you'll be glad to see him returning to our screens here, where he's in his giggly element as the teams are forced to solve a collection of culinary conundrums.

For example: why do tortoises have such big shells? What would you give a butterfly for a special picnic? What two things can you get from a Kangaroo's nipple? And why would someone eat washing detergent for a multi-course Christmas dinner?

And if nothing else, you'll leave this episode with the unlikely mental image of Stephen Fry struggling to cook a cheap microwave dinner. Now that's food for thought.

Episode four of the homicide-themed comedy with an improv edge. Each week, DI Sleet (Tom Davis) investigates crimes perpetrated by phony celebrities, with the help of a real-life famous face. This week it's Dermot O'Leary, who must decide who was responsible for the death of "Amanda Holden" and the kidnap of "Mayor Simon Cowell": care home proprietor "Miley Cyrus", sweet shop magnate "Alan Sugar" or "Jessie J", apparently a martial arts champ. Complete and utter nonsense, cleverly done.

Preview: Murder In Successville, Dermot O'Leary, BBC3

If you haven't become hooked on this bizarre impro-celebrity-reality-TV whodunnit yet I seriously doubt if this week's episode is going to float your boat. But it is a good one.

What to expect from Murder in Successville

Dermot O'Leary, Greg James and Jamie Laing are among the brave celebrities playing detective in BBC Three's new improvised comedy.

The culmination of two weeks' worth of wacky and earnest programming, this charity telethon looks set to be as jape-strewn as ever. Dermot O'Leary's dance marathon concludes, there's a new Mr Bean, and Professor Stephen Hawking performs with David Walliams. All in all, a Friday night in the pub looks more irresistible than ever, but don't forget to put your hand in your pocket first.

Radio Times review

The last time we saw Mr Bean he was bringing the house down at the 2012 Olympics Opening Ceremony, playing one note of Chariots of Fire. Can he (alongside Ben Miller and Rebecca Front) possibly be as funny for 2015's Comic Relief?

Anyone who's anyone from the world of comedy is on BBC One for this comedy marathon. Dawn French dusts off her dog collar to become the Bishop of Dibley (despite some famous rivals); and David Walliams gets in a right kerfuffle as patronising carer Lou, who appears to have a new charge - Professor Stephen Hawking. Miranda Hart, Stephen Fry, Russell Brand and Cardinal Burns also pop by.

There are stunts, dares and the unmissable sight of Dermot O'Leary dancing his socks off (will he survive this danceathon?).

In between all this hilarity are sobering film clips reminding us what this is really all about: donating money.

Radio Times review

Russell Brand almost torpedoed Jonathan Ross's career after the Sachs Incident, and caused convulsions within the BBC that still smart to this day. But the scandal didn't lead to a falling out between the terrible twosome - Brand appeared on Ross's show a year ago and he's back again.

As Brand is never more than a stone's throw from an outraged newspaper headline, he's bound to fulfil expectations as the country's chief Contrarian Comedian, particularly after all of that nonsense about not voting during his Newsnight interview with Jeremy Paxman. Also on the show are actress Goldie Hawn, Dermot O'Leary, presenter of the National TV Awards (22 January), and troubadour James Blunt, who provides the music.

A drum roll, please, for the much-anticipated, always enjoyable offcuts episode. These are the attempts by celebrities to fool other celebrities that ended up on the cutting room floor, not because they weren't funny (they are) but because they were surplus to requirements - or just a bit too guessable.

But we can still revel in Charles Dance's claim that he answers the phone in a Belfast accent or Dermot O'Leary's obsessive approach to stacking crockery. Best of all is a duel between Lee Mack and Richard Osman over whether the latter invented a superhero called Snooker Table Man as a child. We're fairly sure Osman is improvising furiously, but if he is, he's doing a great job...
