TV this weekend: The Rock takes on Graham Norton

The Late Late Show

Friday, RTÉ One, 9.30pm

This week's instalment of the Irish institution sees Ryan interview rising star Barry Keoghan about his journey from inner city Dublin to acclaimed turns in prestige pictures The Killing of the Sacred Deer and Dunkirk. Despite all of his achievements, however, Keoghan seemingly still can't escape the time he killed a cat on Love/Hate. Also on the show is Trinny Woodall, who will be discussing her career as a designer, television presenter and author, as well as her struggles to conceive. We reviewed her new beauty line here. The musical guests are Kodaline, who will perform their emoji-themed new single Follow Your Fire.

On the couch are Dwayne "The Rock" Johnson and Naomie Harris to discuss their new movie Rampage, in which a ginormous mutant gorilla, well, goes on the rampage. "A flying wolf can't make up for awful dialogue and absent humour", was our verdict – let's hope The Rock and Harris right the record tonight. Martin Freeman discusses his appearance in horror anthology Ghost Stories, where he plays a high-flier from the financial sector whose house is terrorised by a poltergeist. Speaking of ghosts, veteran rocker Roger Daltrey performs his new single As Long As I Have You.

The Ray D’Arcy Show

Saturday, RTÉ One, 9.40pm

Irish football legend Paul McGrath will be joining Ray to mark 20 years since his retirement. Ray Houghton and former Ireland manager Eoin Hand will also make appearances to discuss the highs and lows of Paul's 17-year career. Place your bets now about whether there will be at least one chorus of "Ooh, ahh, Paul McGrath". Also on the show is Pamela Flood, who will discuss her return to TV after a 10-year hiatus, with her new show Healthy Appetite. The former Miss Ireland winner will also speak about recovering from social media trolls and her love of the hospitality industry.

Lost in Space

Netflix, from Friday

Danger, Will Robinson! Another ill-advised reboot of the classic sci-fi series about a family stranded somewhere in outer space. We've already had a best-forgotten movie version, and now Netflix are "re-imagining" Lost in Space for a new generation. It follows the adventures of the space family Robinson as they set out in their spacecraft the Jupiter 2 to join a new colony, but are knocked off course and find themselves stranded light years from home. The scheming Dr Smith is played by Parker Posey, and Will Robinson is played by Maxwell Jenkins, the kind of kid Steven Spielberg would give his eye teeth to cast. Can it recapture the hokey charm of the 1960s original, which featured cheapo props, bacofoil-covered aliens and a robot with vacuum cleaner hose for arms? Some things big budgets can't buy.

MasterChef: The Finals

Friday, BBC One, 8.30pm

The latest search for the best amateur cook reaches a compelling climax this evening, with the remaining three pushing themselves to the limit one last time before judges John Torode and Gregg Wallace crown the 2018 victor. Regardless of who triumphs, one thing is almost guaranteed – the winner will have a place at the top table of Britain's culinary industry waiting.

Britain’s Got Talent

Saturday, ITV, 8pm

The big news is not that the talent show is back but that Declan Donnelly will present the "live" shows without his usual sidekick Ant McPartlin, who's stepped back from all engagements after a drink-driving charge. However, they'll both feature in the pre-recorded audition episodes, which were filmed earlier this year, prior to McPartlin's arrest. The usual wide variety of acts, from comedians to contortionists, magicians to martial artists and singers to spoon players, compete to impress returning judges Simon Cowell, Alesha Dixon, Amanda Holden and David Walliams.

Salamander: Blood Diamonds

Saturday, BBC4, 9pm

Chief Inspector Paul Gerardi (Fillip Peeters) is back. During the first run of the thriller, the detective investigated the theft of 66 safety deposit boxes belonging to prominent Belgian figures. Blood Diamonds picks up five years after the death of Gerardi's wife at the hands of secret society Salamander, as he opens an investigation into the murder of Kitangian political refugee Leon Tchite in Brussels. It's not long before he makes a number of alarming discoveries and after learning his prime suspect is dead, Gerardi becomes entangled in a criminal network involving blood diamonds.

My Year with the Tribe

Sunday, BBC2, 9pm

Living in treehouses and using stone tools, the Korowai were only discovered in the jungles of West Papua 40 years ago. Since then they have had to adapt rapidly to the ways of the outside world. This three-part series follows writer and adventurer Will Millard as he visits the Korowai four times over the course of a year, to see if he can get closer to them, to better understand the pressures they face and learn how much of their traditional hunter-gathering lifestyle still exists. What he finds by turns shocks, surprises and confounds him, as he witnesses the last gasp of an ancient way of life.

People of the Year Awards

Sunday, RTÉ One, 9.30pm

The annual awards show, which hands out gongs for good deeds and great sacrifices, was a victim of the Beast from the East, and had to be postponed due to bad weather. Now, with the weather finally settling a bit (we hope), the rescheduled People of the Year Awards is ready to honour the ordinary Irish people who do extraordinary things to help their fellow humans. Gráinne Seoige and Aidan Power will present the event live from Dublin's Mansion House, and awards will be handed out in categories include Young Person of the Year, Community Group of the Year, Sportsperson of the Year and International Person of the Year.
