Joaquin Phoenix

6 of 10
The challenging role of the infamous "Man in Black," Johnny Cash, is played by Joaquin Phoenix—who previously earned an Oscar® nod for his performance in Gladiator. Joaquin masterfully captures Cash's signature sound and truly brings the legend to life, and, like Reese, his stellar performance is already causing Oscar® buzz.

The last time Joaquin appeared on the show, Oprah says he was so nervous he almost didn't come out on stage! Joaquin denies it: "That was a setup," he insists with a smile. "I saw you backstage," Oprah teases, "That was not a setup."
