When he's not attempting to control his powers as Firestorm on The Flash, heartthrob Robbie Amell is busy building up young high school girls' self esteem in the new teen comedy The DUFF. CBS Films has released the final trailer and a new poster for this surefire hit based on the novel by Kody Keplinger. Starring alongside Amell is an ensemble of very popular young stars including Mae Whitman, Bella Thorne, Bianca Santos, Skyler Samuels and the much older Ken Jeong.

Bianca (Mae Whitman) is a content high school senior whose world is shattered when she learns the student body knows her as 'The DUFF' (Designated Ugly Fat Friend) to her prettier, more popular friends (Skyler Samuels & Bianca Santos).  Now, despite the words of caution from her favorite teacher (Ken Jeong), she puts aside the potential distraction of her crush, Toby (Nick Eversman), and enlists Wesley (Robbie Amell), a slick but charming jock, to help reinvent herself. To save her senior year from turning into a total disaster, Bianca must find the confidence to overthrow the school's ruthless label maker Madison (Bella Thorne) and remind everyone that no matter what people look or act like, we are all someone's DUFF.

Check out this epic final look at The DUFF before it hits theaters next month. Every Duff has their day, and Mae Whitman's is February 20. Learn a new four-letter word, then discover for yourself if you know one, have one, or are one...
