The world’s fastest man and (possibly) the world’s funniest man face off in a battle of wits for Pokerstars. The social media campaign, by Gravity Road, sees Usain Bolt and Kevin Hart try their hands at poker skills including reading people, bluffing and managing risk. Activity will culminate in a poker match in the Bahamas next year. The duo’s rivalry began four years ago for Pokerstars with a dribbling race at an NBA All-star celebrity game. The work was created by Andrew Younge and Mitch Sutton.
