A new trailer of what seems to be of the movie adaptation of E.L James' erotic novel "Fifty Shades of Grey" shows real-life couple Kristen Stewart and Robert Pattinson playing the role of Anastasia Steele and Christian Grey in the film.

Official castings for the movie adaptation of E.L James' erotic novel "Fifty Shades of Grey" haven't even begun and already there are numerous trailers on the Internet claiming to be that of the most-awaited and much hyped film. The most recent trailer to be released shows real-life couple Kristen Stewart and Robert Pattinson playing the role of Anastasia Steele and Christian Grey in the film.

The trailer was originally posted in 2011 by "Fifty Shades" fan and YouTube user eldin82 but has suddenly started receiving a string of comments. The 4-minute video shows various sex scenes and "love faces" of both the "Twilight" stars.

While both the stars haven't been on most of the popular "Fifty Shades of Grey" casting polls, Stewart spoke to author Talia Soghomonian last year about the possibility of starring in "Fifty Shades of Grey."

"First of all, they haven't called me or anything, they haven't offered me the part. It's spicy. Yeah. I don't know, I haven't read the whole thing and it's also a highly coveted part everyone is trying to. But I'm pretty daring," Stewart said, according to HollywoodLife.

Some of the comments the video received included:

FlannelPjs1 - "Loved it! It is Kristen Stewart as the female right? If so can you tell me what movie you got her clips from? Thanks and great video :)"

swmrealtor78 - "Wrong in so many ways! Neither are fits to the characters of this novel...AT ALL!! I just cannot get past who they are in their past roles!"

Kiana Jenkins - "This was pretty awesome even though I really don't want(actually can't even see) rob and kris in this movie. But this was well put together; really cool!"
