Adapting a best-selling book for the big screen doesn't always guarantee you a box office hit (see: 'One Day'), but, at the very least, it provides a built-in audience. Enter 'One for the Money,' based on the popular book by author Janet Evanovich. Starring Katherine Heigl as Stephanie Plum, the film is about an unemployed lingerie buyer (Heigl) who goes to work for her cousin, a bail bondsmen. She eventually finds herself going after Joe Morelli (Jason O'Mara), a former lover now accused of murder. Twist! Check out the poster for 'One for the Money' ahead.
