Jamie Dornan Fronts Diet Coke’s Push for Personal Break Moments

Quick listen: Diet Coke’s Jamie Dornan campaign shows why authentic passions work — in under 2 minutes.

Cold-water swimming isn’t for everyone, but Jamie Dornan is diving right in for Diet Coke’s latest campaign.

The actor returns for the next phase of the "This Is My Taste" platform, which celebrates individuality and the small moments that define it.

This time, the focus is on how an average eight-minute Diet Coke break can be a powerful chance to recharge.

Tara Byrnes, senior brand manager for Diet Coke Great Britain, said Dornan’s genuine connection to the sport makes the message land.

“The average Diet Coke break is 8 minutes, creating a small but powerful moment to recharge, and Jamie Dornan brings this insight to life perfectly,” she said.

Dornan reinforced this statement, calling his passion for cold-water swimming a way of "finding a moment for myself, and I try to do it as often as I can." 

This isn't the "Fifty Shades" actor's first collaboration with Diet Coke. 

Last year, the two inked their longstanding deal and launched the first phase of the "This Is My Taste" campaign. 

More Than Just a Swim

Filmed at Shepperton Open Water Swim in Surrey, the hero ad shows Dornan taking a sip of Diet Coke before plunging into icy waters to spend his eight-minute break.

Along the way, he encounters other swimmers making the most of their breaks, from bird spotters to remote-control boaters and paddleboarders.

Other lakegoers show how they spend their eight minutes, with some "bird watching," controlling their toy boats, and paddle boarding.  

The one thing in common? They all take their breaks with a Diet Coke in hand. 

The campaign’s creative approach connects Dornan’s real-life passion to the brand’s message of self-expression.

It rolls out across TV, social media, influencer marketing, and earned media channels throughout Great Britain and Ireland.

To bring fans into the action, Diet Coke is inviting them to design their virtual can through the Coke app, serving as an extension meant to give people a personalized touchpoint with the brand.

The work was developed by Spring Studios with support from Exposure, Ogilvy UK, and Essence Mediacom.

The multi-agency effort reinforces Diet Coke’s ongoing use of celebrity marketing to drive personal connection, while also giving audiences interactive ways to participate.

Our Take: Does Passion Sell Better?

Second time's the charm with Diet Coke and Dornan's latest efforts.

To me, the idea works because it doesn’t feel forced, and the actor's passion for cold-water swimming isn’t just a made-up brand tie-in.

The eight-minute break insight is simple, relatable, and easy to visualize, making it stronger than a generic lifestyle ad.

And when a campaign builds around something genuinely enjoyed by the celebrity, it’s far more believable.
