Hugh Jackman is no stranger to combat spectacles, kicking ass or putting audiences' brains and hearts through the ringer. Be it breaking Dolph Ziggler's jaw or slicing through an army as Wolverine, Jackman has proven he is as much at ease as an action hero as in dramas like The Prestige, Les Miserables and Prisoners.

He's won millions of hearts around the world with his roles and now he can add those of fight fans as well. At UFC 205, Jackman was cageside and even gave Yoel Romero a standing ovation when the Cuban Missile marched outside the cage and saluted his fans. For his role in "Logan", Jackman trained with boxing legend Sugar Ray Leonard to get in shape for his last run as the Wolverine.
