50 Shades of Grey Movie Casting News UPDATE: Anastasia Steele Favorite Emma Watson Talks Lingerie Striptease, 'Hates Doing it So Much' [POLL]

There's enough buzz surrounding who should snag the steamy role of Christian Grey in the highly-anticipated film adaptation of E.L. James' "Fifty Shades of Grey" - but what about his kinky sidekick, Anastasia Steele? "Gilmore Girls'" Alexis Bledel and "Harry Potter" starlet Emma Watson still reign supreme in several "Fifty Shades" casting polls... and it turns out 22-year-old Watson already has some experience in the seductive world of BDSM. Well, sort of. In the 2012 coming-of-age film "The Perks of Being a Wallflower," Watson reenacts a scene from the cult classic "Rocky Horror Picture Show"... which means she had to perform a striptease in some skimpy lingerie. And what did Watson have to say about the somewhat erotic scene? In all honesty, she "hated doing [it] so much." If Watson still isn't very comfortable flaunting some semi-nude skin onscreen, do fans think she has what it takes to play Anastasia Steele (which will likely require flaunting A LOT more bare skin)?

According to Now magazine, Watson recently discussed with the Daily Star how it felt to film the scene in "The Perks of Being a Wallflower" where she had to strip down to her undies and let costar Logan Lerman grab her breast. Apparently, it wasn't all too thrilling.

"I hated doing this so much," Watson said of her "Rocky Horror" reenactment.

If Watson were to star as Steele in "Fifty Shades of Grey," she'd have to let whoever plays Christian Grey (Ian Somerhalder? Matt Bomer? Henry Cavill?) do a lot more than just grab her boob. And she'd have to get pretty comfortable prancing around in her skivvies.

But there's still hope - Watson explained to Empire back in September, "I really get boxed up as 'nice white middle-class girl'... But I've been amazed about how open-minded directors have been about what I might be able to do."

Maybe she's open-minded about what she's capable of doing onscreen, too!

(FYI, Watson's good pal Nina Dobrev once admitted to Ryan Seacrest that the British starlet would definitely be interested in playing Steele if cast alongside Ryan Gosling... read more on that here).
