Jeremy Irons has landed perhaps his most unlikely role to date, voicing the ocean itself in an upcoming feature doc described as a "visionary cinematic odyssey."

The Oscar winner will lend his vocals to the upcoming film "Water People: The Story of Us," which Embankment Films is launching in Cannes.

The film follows six individuals -- a navigator, freediver, surfer, shark whisperer, and two visionary scientists -- each offering a "window into our symbiotic bond with water," according to the filmmakers. These different lives are anchored and threaded together by Irons.

"Water People: The Story of Us" comes from acclaimed artist Maya de Almeida Araujo.

"I am delighted to be part of this extraordinary and important piece of work," said Irons, who himself is a supporter efforts to bring awareness to the issue of plastic pollution in oceans, and fronted the 2012 documentary Trashed about the impact of consumerism and pollution.

"With its distinctive storytelling and scientific foundation, 'Water People' will speak with a voice entirely its own -- a cross-cultural experience designed for global audiences seeking awe, meaning, and immersion," said Hugo Grumbar of Embankment.

"This isn't about the ocean - it's the ocean remembering itself through us," said Almeida Araujo. "The film is about reconnecting with something elemental encoded in our bodies -- a deep wisdom we've forgotten."

Embankment's Nick Taussig ("McQueen," "Audrey," "Churchill") is producing, with Nic Guttridge ("Savage Waters," "The Cancer Conflict"), and are joined by executive producer André Singer ("The Act of Killing," "Meeting Gorbachev," "The Wild Blue Yonder"). Production on the film begins Q3 2025.
