With E.L. James' "Fifty Shades of Grey" novels dominating bookshelves and bedrooms the world over, speculation about the movie version of the erotica trilogy's first book shows no signs of slowing down. And we don't even have a script yet.

Fans submit their favorites for the roles of Christian Grey and Anastasia Steele in polls across the web daily, and even actors are getting in on the game themselves, vocalizing their wishes to be in the movie to anyone who will listen. However, it appears not every actor whose name has been whispered with hot breath by fans is eager to appear in the film version of "Fifty Shades." According to Hollywood Life, Robert Pattinson couldn't care less.

A new source has come out saying of Pattinson's rumored connection to the project, "There isn't even a script, and it is still very much in development with Universal, so he doesn't even have it on his radar... It's a complete out of sight, out of mind situation. He is happy with his current career path and is not in any way bothered by talk of him being in the film. He just doesn't care."

Pattinson was one of the earliest names thrown around when news broke of a "Fifty Shades" movie adaptation, given his popularity from the "Twilight" films, his heart-throb status, and likely due to the fact that James initially wrote her books as "Twilight" fan-fiction. James herself said early-on after the film rights were bought that she just couldn't picture Pattinson in the role of Christian Grey.

And now Pattinson is fighting back. The actor who plays Edward Cullen in the "Twilight" series said he can't believe her book is on the New York Times bestseller list and said he would make her pay for dissing him for the lead role in the upcoming film based on the book.

Pattinson recently spoke with author Talia Soghomonian about the snub, saying, "I think the author has written me out of it. I saw some interview earlier and they went, 'oh, it could never be him.' I'm like, 'Hey, I'm going to make you pay for that!'"

What exactly could the actor do to make James regret her comments? Is Pattinson serious? Or is this is all just a well calculated move to simmer "Fifty Shades" fans' attentions on him while he makes a deal to star in the film? At this point, anything is possible.

Kellen Lutz, Ian Somerhalder, Ryan Gosling, Christian Bale, Matt Bomer, and even Justin Beiber are among many actors' names that have already been mentioned in casting the leading role of Christian Grey, a troubled businessman who seduces an innocent college graduate called Anastasia Steele. "New Girl" star Max Greenfield even said recently he would do full-frontal nudity for the film if he was cast in the lead. 

Telling E! News that he'd happily go full frontal for the role, Greenfield said, "Yeah, that's not a problem... That's not the issue. It's the issue of whether they want to see that much intensity onscreen, because that's what I plan to bring."

Of course, that level of intensity Greenfield's talking about largely depends on what kind of "Fifty Shades" movie producers decide to make. No one involved with the film has commented on what movie rating producers are aiming for.

Since being published last year, "Fifty Shades" has become notorious for its explicit sexual content and controversial portrayal of a relationship involving BDSM. The novel has sold more than 30 million copies in the U.S., and more than 10 million copies to British readers, making James' book the UK's fastest-selling book of all time. All three books from James' trilogy have remained in the top five of The New Yorks Times' bestsellers list for over three months. The first book is currently being adapted into a film by Universal and Focus Features.

James has been tightlipped on confirming or denying any casting rumors. And while names like David Cronenberg, and Bret Easton Ellis have floated around for director and scriptwriter, as of yet, no one is confirmed.
