The Pretty Little Liars actress has said that she is a big fan of the erotica novel by EL James, adding that she has read the entire Fifty Shades trilogy.
The 22-year-old revealed that there's no role she'd rather have than that of the virginal Anastasia Steele, the college student who embarks on a BDSM relationship with businessman Christian Grey.
"I've read every book. I want to play Anastasia," Benson told Celebuzz.
"I like all the characters, but Anastasia? I love her so much!"
Vampire Diaries star Ian Somerhalder said in April that he'd be up for the role of Christian, insisting that the part could be "very, very amazing".
Universal and Focus Features bought the rights to the novel in late March after a bidding war between several studios.
