The latest ad in Nike’s new Unlimited campaign stars Sister Madonna Buder, an 86-year-old triathlete known as the ‘Iron Nun’. The spot, from Wieden + Kennedy Portland, features a witty voiceover by Star Wars: Force Awakens actor Oscar Isaac who expresses incredulity at Buder’s sporting abilities. Isaac has provided the voice for all the Unlimited ads so far, with the campaign launching to coincide with the Rio Olympics (though with no formal acknowledgment of this, as Nike is not an official sponsor). This spot suggests that the Unlimited theme – and the witty tone that goes with it – will outlive the Games, however.
