Louis Theroux v Piers Morgan, in a boxing ring, ding-ding, bell rings, seconds out and let’s go. Would you buy a ticket?

The vaguely disturbing prospect of a Theroux-Morgan clash is raised early doors in Louis Theroux Interviews Anthony Joshua (BBC2, Tuesday, 9pm). “I think I could take him,” says the bespectacled one of the TalkTV host.

Morgan was not the only one being challenged to a fight. “Do you think you could take me?” Theroux asks Joshua.

“Yeah,” says the two-time former world heavyweight champion.

“Seriously, what makes you so sure?” jabs Theroux.

Mercifully for Theroux, Joshua can take a joke.

There’s something about being around boxers that brings out the fighter in otherwise peaceable folk. You can see it in the crowd at the big stadium bouts - women and youngsters roaring themselves hoarse in support of their hero or heroine. Must be all that testosterone in the air.

The sit-down with Joshua is the opener for a second series of Theroux interviews. It is a good “get” as they say in the TV bookings trade. Besides being a global name in sport, Joshua is rich, smart, controversial, funny and articulate. He is also at a crossroads in his career. Having suffered two major defeats, the former Olympic gold medallist is under pressure to get his world title back.

The centrepiece of the hour is a sit down at the London gym where it all started for Joshua. Around this, Theroux packs footage from fights, and some fly-on-the-wall material from his time spent following Joshua around. A boxer’s life, or this boxer’s life anyway, is as much about visiting his auntie in Watford as it is being interviewed by the world’s media.

Theroux the interviewer can bob and weave with the best of them, joking with Joshua one minute, reflective the next. The resulting encounter is fascinating, whether you are a boxing fan or not.

Others receiving the Theroux treatment in this series include Joan Collins and soldier turned whistleblower Chelsea Manning.

Also back for a second series is The Secret Genius of Modern Life (BBC2, Wednesday, 8pm). Professor Hannah Fry, of radio and increasingly television fame, takes another delve into the extraordinary technology that goes into everyday objects, starting with the passport.

Her first stop is the factory responsible for making them, where security is so tight the receptionist is hidden behind a screen and Fry has to wear a zipped, forensic-style suit  to tour the facility (no pockets, see).

Over the course of an hour we learn most of what makes passports so fiendishly difficult to copy. If you’ve ever sat at an airport, idling going through your passport and wondering what this and that feature does, then wonder no longer. Fry has the answers.

A mathematician by trade, Fry has a gift for taking apart complex ideas and processes and making them seem simple. In one typically engrossing segment she looks at the history of facial recognition technology, and where it might be headed in the future. Will there even be paper passports in future? And will we miss the fun of standing in huge queues to have passports checked?

Next week, with the kind of perfect timing you would expect, sees the departure of one broadcast news drama and the arrival of another. On its way back is The Newsreader (BBC2, Thursday, Friday), while heading for a commercial break is The Morning Show (Apple TV+, series finale drops Wednesday).

While essentially about the same trade, the two dramas are different and of their times. In The Newsreader we are in Australia in the pre-internet 1980s, when no-one had to worry about a robot, or a “citizen journalist”, stealing their job. The Morning Show, in contrast, screams noughties New York, where the competition between “legacy media” and digital is cut-throat and it is every journalist for themselves.

The third series of The Morning Show has seen a partial return to form, with Jon Hamm spicing things up as Paul Marks, a Silicon Valley billionaire who might save the UBA network, or he might tear it apart and sell the bits for scrap. It could go either way.

As the third season closes - a fourth is in the pipeline - there are clashes of the titans happening all over the place. Will Hamm get his way, with new love Alex Levy (Jennifer Aniston) as his Lady Macbeth? And what’s the deal with Stella (Greta Lee) and Marks? There’s more to that relationship than him pinching her ideas. And what of fan favourite Cory Ellison (Billy Crudup), the network CEO?

What a beguiling character Crudup has constructed - part business genius, part crazy, and always the most interesting presence in a room. The episode where he took Bradley (Reese Witherspoon) home to meet his mother (played brilliantly by Scots actor Lindsay Duncan) was both chilling and hilarious. After meeting mommie dearest Cory did not seem so strange anymore.
