Lee and Drew have been like brothers ever since adolescence. So when Drew betrays Lee in the heat of a tumultuous night in Glasgow, the two men find themselves entangled in a bitter grudge that went way beyond what they could imagine, as the violence and bitterness of the wrestling ring, spilled over into the real world.

Grudges are typically seen as dangerous, negative emotions. But is there a glimmer of light to be found amid the darkness of resentment? Matthew Syed questions both the hidden values and harsh consequences of grudges.

Featuring WWE superstar Drew McIntyre, ICW champion and professional wrestler Lee Greig, Pr Robert Enright from University of Wisconsin and writer Sophie Hannah.

Matthew Syed kicks off the new season of Sideways with a story of one of the most brutal grudges ever seen in pro wrestling. Matthew asks us to consider when it's time to let go of a grudge and how.

The new season starts on Wednesday 21 February 2024, with other episodes exploring the meaning of photo and video memories, the significance of our names and the creativity of mathematics.

On a summer's day in 1974, Norwegian actor Knut Risan steps up to the mic for a voiceover job. It's for a Cinderella movie that's just been acquired by the Norwegian broadcaster NRK, from the country known at the time as Czechoslovakia.

NRK want him to dub the film into Norwegian. Knut's just having fun. He's doing all the voices, even the young Cinderella. But he's about to become Norway's "Voice of Christmas" when NRK decides to put the film out as part of its festive line up.

Tři oříšky pro Popelku or, as it's often translated, Three (Hazel)nuts for Cinderella, remains an essential part of many Europeans' seasonal viewing to this day. Not least in Norway, where it is shown at 11am on Christmas Eve every year.

Knut's son, Olav, used to feel a little embarrassed around this time of year - everyone knew he was the son of the most famous voice on TV. He'd get strange looks in supermarkets. But today, and in this episode of Sideways, he reflects on the special place his father's voice occupies in Norway's Christmas and in his own family.

Through the story of a film that straddles the line between fairy tale fun and the realities of the Iron Curtain, Matthew Syed explores the origins, meaning and persistence of this cross-cultural tradition and celebrates the role of Christmas films in many families' celebrations, including his own.

Featuring musician Olav Risan and author Kathrin Miebach of the Drei Haselnüsse für Aschenbrödel website. With fairy tale expert Professor Claudia Schwabe of Utah State University and Michal Bregant, Director of Národního Filmového Archivu.

Including clips from Tři oříšky pro Popelku (Czech language version) and Tre nøtter til Askepott (Norwegian language version, featuring the voice of Knut Risan).

David Henty had a talent for art from a young age. He grew up poring over Hogarth drawings. For a long time, it didn’t feel like something that he could easily pursue. But after two prison sentences spent painting as much as he wanted, there was no looking back. David was set on making a living as an artist. The thing is… the only paintings he could manage to sell for any profit, were all forgeries of famous artists like Lowry, Bacon and Picasso.

Matthew Syed explores how David's copy cat approach to art allowed him to unlock his own creativity.

Matthew delves into the world of art forgery to explore how this practice blurs lines between creativity and imitation, and challenges notions of authenticity in the art world. He considers whether copying is actually a necessary step on the way to becoming skilled at a particular craft, and whether forgers - as pranksters - might even qualify as modern conceptual artists, and also ponders how the rise of artificial intelligence platforms might make forgers of us all.

First loves, harsh critics and a celebration of mediocrity - Sideways returns with six new stories about seeing the world differently and the ideas that shape our lives. Presented by Matthew Syed.

In 2014 Angela Maxwell was feeling stuck. She wanted something fresh, something exciting. After a chance encounter she landed upon her goal - she was going to set off on one of the largest adventures imaginable: a walk around the world. She didn't know exactly how the journey would play out, but that was part of the appeal - the whole planet was waiting for her to just take the first step.

In this episode, Matthew Syed hears from Angela about her 6 year walk around the world, from the misery of freezing cold nights, to finding beauty in solitary nights sleeping under the stars. And Angela explores her ideas about courage - after she was raped during her expedition, she chose to continue her journey around the world. Over the six years she walked, she would find deep connection to herself and to others, making lifelong friends and sinking into the places, slowly, just placing one foot in front of the other.

We hear from Susan Houge Mackenzie, a professor of psychology at the University of Otago, about the benefits of adventure to our mindset, even 'micro adventures' which take place much nearer to home, and from naturalist and conservationist Nadia Shaikh, who is a land justice activist working with the Right to Roam campaign, who makes a case that we need far greater access to nature to be able to undertake micro adventures in our local area.

Matthew considers how adventures big and small can clarify our goals for our lives, and asks us to consider whether we ought to all be heading out on adventures a little more often.
