Although the official casting process has yet to start for the film adaptation of E.L. James' Fifty Shades of Grey, that hasn't stopped fans of the racy read from posting up videos of their favorite actors and actresses portraying the romance between Christian Grey and Anastasia Steele.

Although it was initially posted in 2011, a Fifty Shades of Grey fan-constructed YouTube trailer by eldin82 is still getting great responses for its saucy scenes between Twilight's Robert Pattinson and Kristen Stewart.  The four-minute clip shows the two partaking in random romance sessions.

Pattinson and Stewart, who have been on-again, off-again in real life, haven't been brought up as candidates too much lately. However, they still appear to be in the running, as James' characters were originally based off of their characters of Edward Cullen and Bella Swan respectively from Twilight.

According to Hollywood Life, Stewart had previously spoken to author Talia Soghomonian about the prospect of donning the future role of the shy college graduate turned Red Room of Pain participant.

 "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," she said.

Although the producers have yet to attach a director to the franchise, the film is slated for a big screen release in the summer of 2014.

Only time will truly tell who lands the parts of Grey and Steele in what surely will be two breakout roles of his and her careers.
