"Fifty Shades of Grey" movie is coming to theatres in August 2014. The screenplay by Kelly Marcel is ready, and Sam Taylor-Johnson has been announced as the film's director. At the helm of the female creative trifecta is erotic fiction series author E.L. James. A young and sexy actress will soon be named as Anastasia Steele. Kate Beckinsale, Diane Lane and Kate Moss would be perfect as Christian Grey's obsession -- if only they a lot younger.

Here are some of the sexiest, most enigmatic women in Hollywood entertainment. Their younger versions would nail the role of Anastasia Steele as Christian Grey's obsession. Whoever is cast as Ana should review their films and study how they project sexiness through sharp vibe and discreet nuances.

1. Kate Beckinsale. At 39, Kate still looks like the young sweetheart that she was in 2001's "Serendipity." Anastasia Steele is a reluctant sweetheart, but boys see her that way, anyway.

2. Diane Lane. In 2002, Diane was nominated for an Oscar for playing the sex-driven, titular role in "Unfaithful." She was 37-38 at the time. Then she becomes a divorcee rediscovering sex in "Under the Tuscan Sun." She got a Golden Globe nomination. The perfect Anastasia Steele should be convincingly innocent yet smokin' hot. It takes great parallelism or massive some acting skill.

3. Kate Moss. At 39, Moss still has the looks that could turn heads in a gathering. Anastasia has some insecurities with her body because she's rather skinny. But she exudes a strong sex appeal that she's not even aware of. The right Anastasia should be "made under" instead of "made over," just like models have to be styled. But she should pull the innocence with aplomb.

4. Shannen Doherty. At 42, Shannen does not have the youthful vixen vibe of Alexis Bledel and Alexandra Daddario. But she used to be hotter than the two young actresses combined.

5. Katie Holmes. At 34, Katie Holmes is not much older than Alexis Bledel, who is among fan favourites to play Ana Steele. But after being wife to Tom Cruise and mum to Suri, a lot of youth has escaped Holmes at a young age. But the younger Katie, who played Joey Potter in TV's Dawson's Creek, is the perfect Anastasia Steele.

Christian Grey would be drawn by the beauty and raw sex appeal of the younger Kate Beckinsale, Diane Lane, Kate Moss, Shannen Doherty, and Katie Holmes. Whoever gets the Ana Steele role should be at least as gorgeous and smokin' hot as these ladies in their youth - and even now.
