Emma Watson Graduates

"From the first day, Emma was so nice," Erin Wilhlemi, who plays one of Emma's on-screen buds Alice, told InStyle.com. "The first day we I met her, we had our Rocky Horror rehearsal where we had to learn our dance moves. And she got out the car and she was like, 'Hi, I'm Emma!' And I was like, 'Yep, I know,'" she laughed. "She was so sweet and welcoming." Dobrev added that she loved watching Watson perform in her first "American film"—and with an accent, too!
