In an interview with Variety, Flynn admitted she wasn't concerned at all when Theron was given the role, despite the fact that her character is described in the book as being five feet tall and having red hair.  

"I wasn't remotely concerned that Charlize didn't look like Libby because she felt like Libby from the second that she got into Libby's soul," Flynn said. "I couldn't care less that she didn't have red hair."
