WINNER — Kevin Costner: Too many flops extinguished a once white-hot career. After a decade in the wilderness, he’s back. He beautifully eulogized his “Bodyguard” co-star Whitney Huston in a way the encapsulated her dynamic talent, then he scored a ratings smash with his mini-series “Hatfields & McCoys,” earning an Emmy. His reward? A pair of key supporting roles in “Man of Steel” and the Jack Ryan reboot.
