Looking to discover more about the world? From re-examining the impact of World War II to exploring anti-ageing ideas, KrisWorld has a selection of documentaries that challenge the way we understand life, learning, and ourselves. These enlightening shows will leave you thinking long after the credits roll.

World War II With Tom Hanks
So much has been said and written about World War II. How else can a documentary add to the conversation?

Rising to this challenge, this History Channel documentary series presents never-before-seen footage of the war, all meticulously restored and enhanced with modern audio techniques. Narrated by Tom Hanks, each episode combines historical analysis, archival material, and expert commentary to create an engaging and accessible account of the conflict. The restored images feel strikingly immediate, while the human experiences woven throughout the series lend it a powerful emotional resonance.

Rather than simply revisiting military campaigns and political turning points, the series reveals how the conflict reshaped the lives of ordinary people across generations. It is a powerful reminder that history isn’t just a collection of dates and victories, but a tapestry of individual choices, sacrifices, and stories whose impact continues to shape the world we live in today. 

Our Brain
We tend to think of our personalities, memories, and intelligence as fixed. Our Brain argues the opposite.

Across this four-part documentary series, presenter Lawrence Leung takes you through a range of fascinating case studies and the latest neuroscience research that explores how the brain continually reshapes itself throughout our lives.

The series examines everything from how the brain constructs our perception of reality and why intelligence isn’t predetermined to what really happens while we sleep and the surprising science behind happiness.

Rather than presenting these discoveries as abstract research, Our Brain asks what they mean for our everyday lives — whether it’s learning more effectively, managing emotions, or simply understanding ourselves a little better.

Once Upon a Time in Space
BAFTA-winning director James Bluemel continues his oral-history series Once Upon a Time with a journey to the final frontier. Over four episodes, Once Upon a Time in Space tells the thrilling — and at times heartbreaking — human story of space exploration via first-hand accounts and archival footage. Critics have embraced the series, with the BBC calling it a “must-watch” and the Financial Times giving it a perfect score.

Through interviews with the families of pioneering astronauts such as Anna Fisher, the first mother in space, and Ronald McNair, one of the first African American astronauts, the series explores the societal barriers and extraordinary risks these trailblazers faced. It revisits pivotal moments, including the Challenger disaster, the unlikely partnership between Cold War rivals in the Shuttle-Mir programme, and the construction of the International Space Station. By focusing on the people behind the missions, Once Upon a Time in Space delivers a moving portrait of courage, sacrifice, and humanity’s enduring desire to reach beyond the stars.

Making Life on Earth: Attenborough’s Greatest Adventure 
Join legendary wildlife presenter David Attenborough for a fascinating behind-the-scenes look at one of television’s most influential nature docuseries. Directed by Victoria Bobin, Making Life on Earth: Attenborough’s Greatest Adventure revisits the creation of the groundbreaking 1979 series Life on Earth, featuring exclusive interviews with Attenborough and members of the original crew as they recount the challenges, discoveries, and unforgettable moments that shaped the landmark production.

Over three years, the team travelled across 40 countries and documented more than 600 species, including capturing the first footage of a living coelacanth, the prehistoric fish often described as a “living fossil”. Yet some of their greatest dangers came not from wildlife, but from political unrest and conflict, including a coup in the Comoros, detention by the Rwandan army, and threats of imprisonment in Iraq. 

Despite the obstacles, the filmmakers captured some of the most memorable wildlife footage ever recorded, including Attenborough’s famous encounter with a family of mountain gorillas — an experience he later described as one of the most extraordinary moments of his life.

Do You Want to Live Forever?
Humans have always been fascinated with cheating death — or at least slowing it down. Hosted by veteran journalist Tracy Grimshaw and medical expert Dr Nick Coatsworth, this series puts that age-old obsession under the spotlight.

Eight everyday Australians take part in a 12-week experiment to see if they can rewind their biological clocks and extend not just their lifespan, but their ‘healthspan’. From cryotherapy and gene science to biological age testing, the show explores the many ways science is trying to keep us younger for longer.

It’s equal parts fascinating and sobering — a deep dive into not just how long we can live, but how well. Watch to see what insights the experiment brings.
