Jai Courtney
Coming Attractions: A Good Day to Die Hard; Felony; I, Frankenstein
Why He'll Be Big: Spartacus: Blood and Sand fans will recognize the rugged Aussie from his role as Varro, but Courtney who also played opposite Tom Cruise in just-opened Jack Reacher has a full plate for the new year. Most prominent: His role playing the son of ''Yippe ki-yay''-ing John McClane (Bruce Willis) in the fifth Die Hard installment, which opens Feb. 14. If Courtney hopes to take the reins from an iconic action star, he couldn't do much better than Willis. Lanford Beard
