Jonny> Nike ‘Airport 98’. So cool, so effortless and so fun. It’s 90 seconds of magic. Everyone at school was wearing Nike Brazil t-shirts the following week.
The film stuck with me – as I became hooked on Brazil and a couple of years later got a job teaching English in Rio de Janeiro. Amazing that a 90 second film can have that impact.
Jonny> It’s not the most famous ad, but for me, ‘Trees for Tesco’ was a turning point. My first job in the industry was at Lowe, working on Tesco.
I remember sitting in a PPM with director Vince Squibb, watching him bring his vision to life with such clarity and passion. It was the first time I'd been in a room with a filmmaker – and I knew, right then, that I wanted to be on the other side of the table.
Jonny> Working in documentary, writer Michael Lewis is something of a hero. He’s ruthless in the best way – he knows that without a story, you have nothing. That mindset has stayed with me.
Many docs get stuck on themes and subject matter, but he’s a master at finding great stories and great characters.
I love hearing him interviewed – his passion is infectious, and it’s heartening to know how hard he works to take a nugget of an idea and turn it into a story.
‘Moneyball’, in particular, could have been dry in the wrong hands, but instead, it’s a masterclass in storytelling.
Jonny> A wedding video. Looking back, it was the best training for documentary filmmaking.
You’re capturing raw emotion, working in real time, and there are no second chances.
Goosebumps, tears, and joy – bottled in the moment. That skillset still serves me today.
Jonny> Exploitative filmmaking. Documentary is a privilege – it’s built on trust, authenticity, and pride in the final film. Many of the people we’ve filmed – refugees, athletes, remote communities – we still keep in touch with. Some are lifelong friends.
Jonny> Louise Osmond’s documentary ‘Dark Horse’ is a beautiful gem of a film. A backwater Welsh mining community buys an unloved racehorse and takes on the elite. It’s one of those rare, perfect true stories – and I wish I had found it! It has everything I love – an unlikely dream, a defiant underdog, and a forgotten community finding its pride again.
Jonny> ‘Black Cab Sessions’. Jono (co-director) and I feel like our filmmaking careers were born in the back of a cab.
The idea was simple: one song, one take, one cab. Raw, unguarded, totally unlike a glossy music video – just an intimate connection between artist and audience. It took off. Nearly 400 sessions, a global audience, a Channel 4 TV series travelling across America, and a string of cultural awards.
Brands like Ray-Ban, adidas, and Red Bull started coming to us, and suddenly, we had a career. We often say ‘good things happen when you make good things’ and this was where that belief was forged.
Jonny> ‘The Way of the Wildcard’. Red Bull is known for stunts and spectacle, but this series was different. It leaned into human storytelling – sporting mavericks who saw the world differently and refused to be defined by expectations.
It was also one of the first Red Bull projects to be recognised in major film awards. That meant a lot.
Jonny> There’s probably a few over the years. Jono (co-director) and I met at university… Some of the early films we made together on mini-DV are very funny looking back – mainly for the haircuts.
Jonny> ‘Hustle and Run’ – a documentary we just launched for Channel 4.
At a time when the world feels fractured, this is a film about the power of community. It’s about people (and pets) coming together around a shared passion – flyball, the most joyful, exhilarating sport you never knew you needed.
It’s got everything I love – an underdog story, a dreamer defying the odds, a ragtag team rallying behind them. Heart, grit, and goosebumps. It’s exactly why I got into documentary filmmaking in the first place.
