In his joyous new comedy Finding Father Christmas, the star is on a mission to prove Santa really exists – and he’s got Stephen Fry to help him! He talks magic, trampoline mayhem and finally getting behind the wheel of a car

It’s time for a father to have an awkward conversation with his teenage son. No, not that one. This is far worse – Chris is 16 and still believes in Father Christmas. He needs to know the truth: all the presents, the fake snow on the roof, the soot in the grate, it was all his dad. “You’re Father Christmas?” says Chris, astonished. “You bring joy and happiness to billions of children all over the world?”

In Finding Father Christmas, Channel 4’s funny and moving comedy, Chris, played by Lenny Rush, bunks off school and sets out on a mission with his older cousin Holly (Ele McKenzie) to prove to his sceptic dad that Santa is real. Poring over a photograph taken at a celebrity party, Chris thinks he has identified four people who may have secret links to Santa – Stephen Fry, mathematician Prof Hannah Fry, the space scientist Maggie Aderin-Pocock and SAS: Who Dares Wins star Jason Fox. Finally, he follows clues to a secret secure facility in Milton Keynes and breaks in with the help of a mini trampoline and the magic of television (a bungee cord). “It was terrifying, but so much fun,” says Rush of the stunt. “I feel like if I was offered [to do it] and I said no, I’d kick myself on the way home. I wanted to give it a go and I’m happy I did. But there was an element of fear.”

The actor’s publicist and manager worked with him for more than 30 years, before his death in 2023. They discuss the man behind the headlines – and why they are continuing his mission to help others struggling with addiction

Watch the third season of Friends, writes Matthew Perry in his memoir, and you can see how thin he had become by the end of it. “Opioids fuck with your appetite, plus they make you vomit constantly,” he writes. Look again, and yes – his fragile wrists emerge from a shirt that looks as if he has borrowed it from someone far larger, his trousers hang off him – and it’s unbearably sad now, with the knowledge that addiction would kill Perry nearly 30 years later, at the age of 54. At the time, most people watching probably wouldn’t have noticed, dazzled instead by Perry’s sharpness and immaculate comic timing as Chandler Bing, the show’s dry wit. He was having to take 55 Vicodin pills a day – an opioid - just to function and avoid terrible withdrawal symptoms, but he was never high while he was working, he writes in Friends, Lovers and the Big Terrible Thing, which came out in 2022. He just had to make it to the end of the season so he could get help. Had the series lasted for more than its 25 episodes, he thought it would have killed him.

That was the first time Perry went into rehab. He was 26, and one of the biggest stars in the world. There would be more than 65 attempts to detox from drug and alcohol addiction over the next decades until his death in 2023. Last week, a doctor was sentenced to two-and-a-half years in prison for supplying ketamine in the lead-up to Perry’s death (though not the ketamine that killed him); three others who have pleaded guilty will be sentenced in the coming months.

Until she reached her 50s, the actor was a constant presence on stage and screen. Then the offers disappeared. Now, as her renaissance continues, she is taking on Mrs Malaprop in The Rivals

After six decades as an actor, Patricia Hodge says she still gets nervous before a play opens. “I think nerves are always the fear of the unknown,” she says. “Particularly with comedy, where there is no knowing how the audience will react: you’ve got to surf that.”

We meet on a sunny winter morning at the Orange Tree theatre in Richmond, south-west London, where Hodge is about to appear in The Rivals, to celebrate the 250th anniversary of the Richard B Sheridan play, in which she plays the ironic – sorry, iconic – Mrs Malaprop. “You’re sort of in a tunnel, your entire being is focused on this,” she says. She was here in rehearsals until 11pm the night before. Today, she is sitting at a table with a large coffee. Does she enjoy this bit, the putting together of a play? “I think it’s love-hate actually. The process is really why I do theatre.” She says she finds it energising, “but it’s also very trying, and you just don’t want to be left with your own limitations”.
