I’ve spent more than two decades working at the intersection of creativity, audience psychology and commercial strategy; releasing films, building campaigns, and helping producers find the right path to market.
My work covers every stage of a film’s lifecycle: early-stage positioning from script, packaging for festivals and sales, campaign design and creative assets, and distribution execution across theatrical, hybrid, and digital platforms. I combine an operator’s mindset with teaching, which means the strategies I recommend are ones I’ve used in real campaigns.
Magus Films brings together three complementary strands: development & producing support, positioning-led creative, and boutique UK distribution. We keep our slate small and our work focused so each project benefits from attention to craft, creative clarity, and clear commercial thinking.
I also teach and write because practical knowledge scales. The book, the lectures, and the Substack are tools to help filmmakers avoid common marketing mistakes and adopt practical, repeatable approaches to building an audience.
