The actor was announced as the campaign's first Team Ocean Captain at a New York City Climate Week event on September 24, 2025.

He described the ocean as something that connects everyone, highlighting its universal appeal.

The campaign includes a roster of Team Ocean Captains such as Napheesa Collier, Kelvin Beachum, Brent Suter, Ezra Frech, Katherine Barkman, and John John Florence. These athletes, teams, and performers aim to connect cultural influence with action for ocean conservation. The campaign is supported by various sports and entertainment entities, including the Seattle Seahawks, Cleveland Monsters, United States SailGP Team, and Team USA Artistic Swimming.
