Robert Llewellyn

And a few other notes, both low and high: why no women on Chain Reaction (R4), where public figures (usually comedians) get to interview other public figures (usually comedians)? Yes, we've had Catherine Tate and Arabella Weir, but we're six series in now. This week's programme, the first in the new batch, began with Robert Llewellyn interviewing Dave Gorman. Gorman was far too pleased with himself; but then, that's the nature of this self-congratulatory series. You may as well call it Blowing Smoke.

Robert Llewellyn, of Scrapheap Challenge, interviews Dave Gorman, comedian, of Are You Dave Gorman? Is he obsessive? asks Llewellyn. Suppose so, says Gorman, but real obsessions make good shows. Is it all a bit egotistical? Gorman asks himself, then answers it, saying not really. The Daves in his adventures are alter egos. He started off as an ordinary stand-up with jokes, was inspired by Ian Dury's song Reasons to Be Cheerful to branch out into real-life jaunts. Who will Gorman interview next week? If anyone's still listening by then...

Back when this ramshackle quiz was a bonkers night out at the Edinburgh Festival, the site of deadpan comic Tim Key (nearly) falling off his track-rolling quizmaster chair routinely had us in stitches. Now, said quiz, which asks ludicrous questions then asks text-messaging service AQA to answer them, has made the jump to TV. Mark Watson is the host and tonight's baffled guests are Julia Bradbury and Red Dwarf's Robert Llewellyn.

'Red Dwarf' stars are 'best mates'

Robert Llewellyn has revealed his joy at being reunited with his former Red Dwarf co-stars.

For Craig Charles, one of the highlights of making this three-part special was finding he could still fit into the leather jacket and trousers that he wore as Dave Lister 21 years ago.

All the cast (minus Holly in either of his / her incarnations) are here, too - Chris Barrie as hologram Arnold Rimmer, Danny John-Jules as Cat and Robert Llewellyn as Kryten - for this much-anticipated reunion.

The sci-fi comedy ran for eight series on BBC2 between 1988 and 1999, picking up an International Emmy on its intergalactic travels. So well done to Dave (the channel, that is, not Lister) for doing what the BBC never managed - getting the crew of the Red Dwarf back to Earth.

Actually though, that's down to guest star Sophie Winkleman - a comedy favourite thanks to her Peep Show appearances. She plays the new holographic Senior Science Officer Katerina Bartikovsky, who works out a way to send Lister to a new dimension.

Katerina's arrival is bad news for Rimmer - this spaceship's not big enough for two holograms - but good news for Lister as, being the last surviving human, it will be his job to go forth and multiply.

Tonight's episode might feel a bit flat as the crew battle a sea monster but, in the next two instalments - tomorrow night and Sunday - there'll be plenty of surprises as they arrive on Earth in the year 2009 and find themselves on a Manchester street you'll certainly recognise.

Behind the scenes on Red Dwarf

At the refreshment table, the use of a straw allows Robert Llewellyn, reprising his role as the robot Kryten, to sip coffee without dribbling on to his rubber mask.
