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 work has always been conservation focussed, seeking to create awareness. In 2018 we donated our work to the education system in Ireland and our award winning series, ‘Ireland’s DEEP ATLANTIC’ now features on the secondary school curriculum, the first TV documentary to be used this way.

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.

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.
