Winter has arrived, and Nike has employed the man from Boyle, county Roscommon to deliver the news in their latest ad campaign.

Chris O’Dowd plays the role of a TV news anchor predicting the end of civilisation as a result of plummeting temperatures, something only Nike’s new clothing line can prevent.

The actor does a pretty convincing Ron Burgundy impression as he hyperbolically describes the effects of the cold on the human body. 

And yet O'Dowd's dire warnings are completely at odds with what's shown on screen, as we see cold-weather athletes going about their business—with their brains and extremities in perfect working order.

The film is the first instalment of Nike's Choose Your Winter campaign and also features football star Aaron Rodgers and soccer player Clint Dempsey as well as figure skater Gracie Gold and snowboarder Johnnie Paxson.
