Sea Fever Productions ocean based film / TV company.

Ocean Explorers

Sea Fever Productions Multiple Awards-winning, Creative, Natural history documentaries from the North Atlantic since 2006.

Our documentary films have now been broadcast in forty countries distributed by BBC Studios Worldwide and Blue Ant Media.

We began in 2006, trying to tell stories of our connection with the natural world and our cultural heritage in a creative, cinematic form.

But witnessing so much damage and biodiversity loss in our ocean, we felt compelled to tell conservation-focussed stories, long before this became popular in blue-chip nature films.

…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.

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.

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.

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.
