Forensics: The Real CSI
Every crime leaves a trace – and in this compelling BBC series, the smallest details can crack the case. From microscopic blood spatter to a muddy footprint or a single fingerprint on a discarded can, forensic science is at the heart of modern detective work. Filmed with West Midlands Police, the UK’s second largest force, the series follows an elite team of forensic experts as they use cutting-edge techniques to uncover the truth behind thousands of crimes every year.
Denis edited 5 episodes across series 2 and 5 of this returning series, revealing how science brings criminals to justice.

24 Hours in A&E
24 Hours in A&E tells the stories of life, love and loss that unfold every day in one of the UK’s biggest emergency departments. Using over 100 fixed-rig cameras, each programme follows patients who are treated in the same 24-hour period.
Over 300 episodes of this much loved series have been produced since it launched in 2011, featuring King’s College Hospital in South London. In 2014, the series moved across the capital to St George’s Hospital before moving to it’s new home at Queens Medical Centre in Nottingham in 2021.
Winner of an RTS Award for Best Documentary in 2012. 24 Hours in A&E has also been nominated for Best Factual Series in the BAFTA Awards in 2013 and again in 2019. Additionally, it has been nominated for a Grierson Award, a Broadcast Award, and multiple TV Choice Awards, as well as winning a Televisual Bulldog Award in 2013.

Inside the World’s Toughest Forces
Three former Special Operations soldiers travel the world on a mission: to go deep inside the most elite and secretive military units on the planet. US Army Ranger Cameron Fath, British Special Forces operator Dean Stott and US Navy Seal Ryan Bates, have all seen combat and served their countries with distinction but now they have a new challenge – finding out what it takes to operate at the highest level alongside 8 different elite forces across the world in very different environments.
Each episode sees Cameron, Dean & Ryan live and train with each unit, learning how they operate in often extreme environments: from learning to survive in the arctic, attacking a terrorist camp in the desert, rescuing hostages in the swamps, and taking back a ship from pirates. Our hosts get to grips with the forces’ weapons, kit and tactics as well as very different rules of the game before carrying out a final military mission alongside their new brothers in arms.

In My Own Words: Jilly Cooper
In My Own Words is a contemporary BBC series that gets inside the creative minds of some of Britain’s leading lights.
This episode celebrates a supremely insightful, funny and sharp-eyed chronicler of our lives and times: Dame Jilly Cooper.
Having sold over 12 million books, few other British writers have so consistently held up a mirror to the British as we really are – to our sex lives, class obsessions and the messy reality of our relationships. What does her extraordinary half-century of work reveal – not just about her world but about ourselves?

Patrick Kielty: One Hundred Years of Union
On the 100th anniversary of its creation, Patrick Kielty explores what the future holds for Northern Ireland, in an authored documentary for BBC One. He investigates why a new trade border in the Irish Sea has led to violent protests, sparking fear among some of a return to conflict, nearly 25 years after the end of the Troubles; a conflict which claimed thousands of lives, including that of his father Jack Kielty.
In this very personal film, Patrick’s focus is on a new generation born long after the ceasefire, as he tries to understand what is driving this new wave of unrest, particularly in Loyalist communities. He also explores why some feel that a united Ireland could now be on the horizon and how the trauma of Northern Ireland’s past is shaping its future.

SAS: Who Dares Wins
SAS: Who Dares Wins takes a group of civilian recruits through the most gruelling stages of the SAS’s secret selection process. Ex-Special Forces soldiers push the recruits to their limits in extreme and unforgiving terrains in the ultimate test of their physical and psychological resilience.
As the recruits progress through the course, they discover harsh truths about themselves. For many it will prove a life-changing experience, but who among them has what it takes to make it through to the end?
