The "Dark Knight Rises" beauty portrays tragic prostitute Fantine in the upcoming film adaptation of the hit musical and Jackman is convinced she has a real shot at taking home a Best Actress Academy Award at next year's ceremony, reported Daily Star.
"After Annie's first day of rehearsal, I said to Tom, 'You can just turn the camera on, digitally remove the script from her hands, and she's going to win the Academy Award," he said.
And Jackman, 44, was not the only one left awestruck by Hathaway's vocal abilities. Actress Amanda Seyfried, who plays Fantine's daughter Cosette in the movie musical, says, "As soon as I heard her sing, I was like, 'Oh! I've got to up my game big time.'"
