The Three Tenors: From Caracalla to the World (Sky Arts, 7.30pm)

IT is generally regarded as the most successful classical concert ever. Thirty years ago, Luciano Pavarotti, Placido Domingo and José Carreras performed together, with conductor Zubin Mehta, for the first time as the Three Tenors in the thermal baths of Caracalla to mark Italy’s staging of the FIFA World Cup. Over 1.6 billion people watched the concert worldwide – and it catapulted classical music into a completely new dimension. To mark last summer’s 30th anniversary of the concert, this film shows the highlights of the show and its sequel in Los Angeles. And, for the first time, Domingo, Carreras, Mehta and Pavarotti‘s widow Nicoletta Mantovani talk about the trio’s rivalries and friendships.

Agatha & Poirot Partners in Crime

Agatha & Poirot: Partners in Crime (ITV, 9pm)

The broadcaster claims this documentary is celebrating 100 years of Hercule Poirot, but seeing as he made his first appearance in Agatha Christie’s debut novel The Mysterious Affair at Styles in 1920, it’s a year late. But never mind, we won’t hold it against the schedulers. Richard E Grant is the man in charge of the proceedings; he explores the author’s extraordinary life, linking some of its events to the cases her famous Belgian detective solved, the people he met and the locations he visited until she brought an end to his career in 1975’s Curtain. Grant also catches up with some of Christie’s celebrity fans and investigates Poirot’s most famous outings, including Murder on the Orient Express and Death on the Nile, both of which have recently been filmed by director and star Kenneth Branagh.

Intruder (C5, 9pm)

As with its recent hit drama The Drowning, Channel 5 is broadcasting Intruder across four consecutive nights, allowing tension to build but without making viewers wait too long to see how matters pan out. Tom Meeten and Elaine Cassidy play Sam and Rebecca Hickey, who appear to live the perfect life in their rural self-build modern home in the West Country. However, their idyll is shattered when two teenagers break into their home and, in a rage, Sam stabs one of them to death as he’s trying to escape through a window. They realise that Sam could be tried for murder, and decide to stage the scene to make it appear he killed the intruder in self defence. It initially appears to work, until family liaison officer Karen Bailey (Sally Lindsay) grows increasingly suspicious…

Louis Theroux Shooting Joe Exotic

Louis Theroux Shooting Joe Exotic

Louis Theroux: Shooting Joe Exotic (BBC2, 9pm)

Last week, Ross Kemp jumped on the bandwagon of Tiger King’s success by presenting the first of two documentaries about Britain’s own big cat-owning residents. Now Louis Theroux is going one better by speaking to Joseph Maldonado-Passage, better known as Joe Exotic, the man at the centre of the hit Netflix series. They have, however, met before. Theroux spoke to Joe while making America’s Most Dangerous Pets, but it’s fair to say that life has changed a lot in the intervening decade. Joe is still living in Oklahoma, but rather than residing at his personal zoo, he’s behind bars in a federal prison, having been found guilty of animal cruelty and of plotting a murder. Theroux also catches up with others from his original programme and meets those working to get Joe out of jail.
