50 Shades of grey for Halloween 2012?

The 50 Shades of Grey books by EL James will soon be made into a movie and the interest for the cast has drawn some big name actors and actresses.

It has also produced several celebrities giving opinions on who they would like to see star in the roles of Christian Grey and Anastasia Steele.

Fans, too.

The book has also sparked a good deal of interest for Halloween costumes for 2012, expect to see some of the book's kinky themes show up at adult Halloween parties this year.

CBS Miami explains the possible costume choice for daring adults:

"Ok, this one is definitely for the grown-ups. There was just one book that hit the stands this year that had “Sexy Halloween Costume” written all over it. “50 Shades of Grey” is the perfect couples costume for those grown-up Halloween parties. Since you can’t go nude, wear a bikini and let your “Mr. Grey” hold the rope."

Everyone seems to have an opinion on the cast, even celebrities.

Gather notes:

"Leona Lewis is such a big fan of 50 Shades of Grey that she recently named her picks for Christian and Ana in upcoming 50 Shades movie - Chris Brown and Taylor Swift. So apparently Leona does like for her guys to be a little rough."

Ashley and Mary-Kate Olsen's little sister Elizabeth Olsen has spoken out as well - though she says she will pass as Anastasia Steele in the upcoming movie Fifty Shades of Grey.

More Fifty Shades of Grey notes…

Earlier it was revealed that Will.i.am's song lyrics inspired the 'Fifty Shades of Grey' book and its subsequent novels.

Author EL James has revealed the inspiration behind her raunchy writing is the Black Eyed Peas frontman.

The novelist told how she listened to his band while writing her worldwide bestsellers.

The 48-year-old woman told The Sun newspaper: "I have songs that I write sex to. One of them is the Black Eyed Peas' 'Sexy'. That is a very sexy song."

The track, from their 2003 album 'Elephunk', features lyrics like: "For you I'm a fanatic, I'm an addict, your sexy antics turn me on like automatic."

James, who has raked in a fortune from her books, confessed her musical tastes at the launch of her 'Fifty Shades' classical album.

She added that part of the books' success was that the covers are "discreet", allowing fans to read them anywhere.

She said: "I designed the covers because in my early 30s I read a lot of romantic fiction when I was slogging in and out of London on the Tube. But they had these horrible covers with women with clothes falling off.

"I hated that and I had to bend the covers back. So I designed really discrete covers so that no one would ever know it is salacious."

She added electronic books had also helped, explaining: "E-book readers have been very liberating for people because they can read whatever they like with no judgment."
