When Gosling didn't nab PEOPLE's Sexiest Man Alive title in 2011, there was no one more devastated than Clooney, who cast the hunk in the Ides of March and groomed him for the title. "It's gotta be Ryan, don't you think?" Clooney said, adding, "I called up Brad Pitt and we worked with him for weeks on the walk, we told him how to train, everything." Of Clooney, Gosling said, "He's equally as funny as he is serious, all at the exact same time. He's just a great guy."
