The more we see and hear about a post-Harry Potter Emma Watson, the more excited we get about the 22-year-old starlet's future.

Her upcoming flick Perks of Being a Wallflower includes what will likely be a very memorable sceneshe and her costars reenact portions of the Rocky Horror Picture Show.

"We sat around in those Rocky Horror outfits for like four daysjust like everything hanging out," Mae Whitman, the Parenthood star who plays Mary Elizabeth in Perks, told me at the Hit & Run premiere. "I wouldn't say it's too risqu, but it's definitely more Hermione than you've ever seen before."

How "bad" is Emma Watson?

The cast also includes Logan Lerman, Ezra Miller, Nina Dobrev, Kate Walsh and Paul Rudd, among others.

"It was crazy," Whitman said of the shoot. "It was probably more of a high school experience for me than my high school experience was. We were all in the same hotel on the same floor and we would work all these late hours and come back and have jam sessions till 7 in the morning.

"It was so fun," she added. "It was so fun and we loved each other so much a! nd that' s really what that story's about, kind of connecting with people in that way. So [director and writer Stephen Chbosky] definitely cast it right. It was a very special experience."
