The 25-minute film Defeating Oceans Seven was shown to critical acclaim on Friday at the Corona Fastnet Short Film Festival.
Directed by Wolfgang Merkel and produced by Red Bull Media, the documentary is based on live footage of the Corkman as he overcame the Oceans Seven challenge — the swimming world’s equivalent of the Seven Peaks mountaineering challenge.
The film comprises eye-catching footage of the Ballydehob native as he battled dangerous waters to become the first person in history to achieve the target.
The Oceans Seven challenge sees swimmers attempt energy-sapping long-distance journeys in waters off Japan, Hawaii, New Zealand, the Straits of Gibraltar, Los Angeles, England, and Scotland.
Despite competition from other rivals who were also aiming to seal their place in the record books, Mr Redmond — a 48-year-old father of two — completed the quest last summer.
The documentary, which has also been shown on the Discovery Channel in the US, follows the Corkman on the last leg of the journey through the Tsugaru Strait in Japan last July.
Underlining the stress his body was under, the film’s makers said capturing the footage required a team of five cameramen “hanging on for their lives in rough seas” on a nearby boat as Mr Redmond swam.
Since becoming the first person to accomplish the feat, Mr Redmond has remained typically modest about his achievements.
After being named World Open Water Swimming Association man of the year in a global online poll in January, he simply said: “I really think its Cork’s award and Ireland’s award. It’s been a great year. To get the three channels done and finish it out and beat the rest of the great swimmers around the world it’s just been an amazing trip for me and my team.”
Of the documentary, he said: “It brings every second of the insanity and the madness that we went through out there, back vividly to the present day.
“They have made a marvellous job of it and I’m eternally grateful to see this. I can’t wait for everyone else to see it.”
