British visual artist and filmmaker, Sam Taylor-Johnson, was confirmed to direct the film version of EL James's best-selling erotic novel, Fifty Shades of Grey.
As the speculation over the casting continues, reports emerged that the 46-year-old's husband, Aaron Taylor-Johnson might take up the role of Christian Grey.
Aaron starred in Sam's one and only feature film - Nowhere Boy, which is a 2009 biopic on late Beatle John Lennon's younger days.
At the Comic-Con festival in San Diego, the Anna Karenina actor talked about playing the young billionaire entrepreneur in the movie and working with his wife again.
"I'd love to work with Sam again, no question, without a doubt," Aaron said, "I think she's such an incredible director and she's got such an incredible vision. And especially for something like this (which) she can do - no pun intended - with her hands tied behind her back and blindfolded."
However, Aaron revealed he is not interested to take up the role of Grey.
"For me, Christian Grey - I just don't fit the bill for Christian Grey, you know?" he said.
Meanwhile, Vampire Diaries star Ian Somerhalder, a fan favourite for the role of Grey is reportedly out of the casting list. Us Weekly claims James, who was at the Comic-Con confirmed the news.
An insider told the publication, "E.L. was at a Comic-Con party July 20 telling people the part won't go to Ian."
It was recently announced that the film will be released in North America on 1 July 2014.
