It's on later in the year than usual, but The Apprentice is back. Yippee! For the tenth series Lord Sugar and his producers have done a little tinkering with the format - enough to keep it fresh but without upsetting its dedicated fans, of which I am one - and last night 20 hopefuls lined up in the boardroom (instead of 16, as previously) to hear him run them through their paces.

Michael Keaton, Val Kilmer, George Clooney, Christian Bale and (coming soon) Ben Affleck have all had a go at playing the fully-formed Caped Crusader, though for some Adam West's ludicrously campy Sixties incarnation remains the score to beat. But apparently that's still not enough.

Cosmonauts: How Russia Won the Space Race (*****) arrived at a strange time. With its remarkable accumulation of Soviet archive material and interviews with key figures, including Alexei Leonov, the first man to walk in space, the programme must have been a long time in the making and the fruit of lengthy collaboration of a kind that might not be so readily forthcoming today. Michael Lachmann’s film rightly reminded us of the achievements of the Soviet space programme and how in many areas it “beat” the Americans.

It was tempting to assume that Homeland [****] had died along with Damian Lewis's Brody, last seen dangling gruesomely from a crane in Tehran at the end of series three, but this tense and uncomfortable season-opener suggested that all may not be lost. Carrie Mathison (Claire Danes) has been promoted to CIA station chief in Kabul, but she's finding that the personal price of professional success is growing exorbitantly high.

It feels as though 2014 was the year in which the Twitter generation finally woke up and realised what it had done. For five years a quiet, unassuming baking competition had risen through the ranks to become the most polite BBC One ratings juggernaut in the corporation’s history. Frankly, the world was ready for a bearded ginger Irishman to throw his baked Alaska in the bin and storm off into the great British countryside.

Brian Cox has a very beguiling way of expressing quiet wonder. He’s taken on the very largest of subjects in Human Universe, extending traditions of science and natural history broadcasting towards a wider study of how the human race has come to be what it is, where it came from and where it may be going, and he doesn’t raise his voice on a single occasion. Other BBC presenters carried away by their subject matter could certainly take a hint.

Two moments of physical comedy from British sitcoms regularly fill the polls of viewers’ favourites: Basil Fawlty thrashing his broken-down car with a branch, and Del Boy falling sideways through a just-opened pub bar.

Cats have had a harder time adapting to humans than humans to cats, as this remarkable examination of contemporary feline habits points out. It is not always easy changing from wild animal to feline friend, as the programme put it. Nocturnal hunters now have a life in the daytime, but they are still solo rather than pack animals. While a dog will cling to his pack – his human family – the cat susses out the physical territory on its own, seeing how safe it is and where to hide if necessary.

Despite a 47-year history which has taken them from pomp to pop and established them as a top-selling global institution, there's still a lingering sense that Genesis don't think they've been taken seriously enough. This was detectable in Phil Collins's comment included here that "we're just popular and there's nothing wrong with that... I won't take the credit and I won't take the blame."

So we're off for another blast of between-the-wars ultraviolence with the Shelby gang from Birmingham, once again soundtracked by incongruous electric blues music. Time has moved on from the immediate aftermath of Great War hostilities and now we're into the Twenties, which are roaring as if they're in agony. The baleful Tommy Shelby (a curiously shaved and bleached-looking Cillian Murphy) is aiming to undertake "business expansion" by extending the Peaky Blinders' racketeering tentacles down to London.
