Inspired by nature

Based in Lahinch on Ireland’s Atlantic seaboard we produce natural history, wildlife and creative documentaries.

We began in 2006, trying to tell stories of connection with the natural world and our cultural heritage in a creative, cinematic form. Our multiple awards-winning documentary films have been broadcast and screened across the planet in more than thirty countries.

Our work has always been conservation focussed, seeking to create awareness. We donated our work to the education system in Ireland and ‘Ireland’s DEEP ATLANTIC’ now features on the secondary school curriculum.

NORTH ATLANTIC
The Dark Ocean

Spring 2023

‘Hugely ambitious natural history TV series featuring iconic creatures and marine life of the North Atlantic. Presented by Irish underwater cameraman Ken O’Sullivan, with thoughtful, impactful storytelling showing the lives and troubles of some of our greatest wild animals.’

Stories from the Deep

Ken O’Sullivan’s critically acclaimed book of narrative stories, poetry and incredible photographs documenting his time exploring the North Atlantic.

‘A beautifully written book; nostalgic, informative, exciting and lyrical.’

Sue Leonard – Irish Independent book review

‘Soulful, absorbing and powerful.’

Diarmaid Ferriter – UCD

‘O’Sullivan’s writing is as weightless as the plankton that float around him.’

Ireland’s Deep Atlantic

…the footage Ken and his crew get of the deep ocean and its inhabitants is extraordinary, up there with anything to be seen in The Blue Planet or any other outstanding nature documentaries, and O’Sullivan’s passion for his subject is both evident and admirable.

The Silver Branch

Breathtakingly lovely. Costello’s rich images offer elegant underscores to the subject’s pastoral verse. The film does trust that we share its subject’s passion for nature, but it will win over even those agnostic about the philosophy.

Ireland’s Ocean

…stunning underwater series. It looks superb, with dreamy shots of astonishingly beautiful jellyfish, giant basking sharks and hundreds of dolphins.

Critically acclaimed

Captured the attention of the entire country last night with the first part of the eagerly-awaited documentary series, Ireland’s Deep Atlantic.

The Irish Independent

Stunning… dreamlike… fascinating four-part ocean wildlife series explores the spell-binding diversity of the marine life living around the Irish coast and asks some thought-provoking questions about the wildlife that share our waters.

The Irish Examiner

Film making as it should be in Ireland, finding the universal in the local – with a sure footedness that is most unusual, magical… a unique and an important cinematic gift.
