[From MTV News] Emma Watson knows a thing or two about "American Talk." Sure, she mastered the accent for her turn as love interest Sam in the big-screen adaptation of Stephen Chbosky's "The Perks of Being a Wallflower," but we here at MTV News like to think we had a hand in educating the Brit on the finer points of the Yankee accent long before.

As you may recall, in late 2010, the cast of "Harry Potter" took a break from Hogwarts to enroll in Josh Horowitz's prestigious language school, otherwise known as "After Hours." Stars Watson, Daniel Radcliffe, Rupert Grint and Tom Felton learned the "right way" to speak, reciting practice phrases such as "the Olive Garden," "Glenn Beck" and "boo-yah." A sequel soon followed, and now Watson, along with "Perks" castmates Logan Lerman and Ezra Miller, is starring in the third installment, "American Talk: When Cultures Collide."

The format of the show had to be modified, however, considering Lerman and Miller are American (that'd be cheating after all!). So this time, while Watson perfected phrases like, "Wassup! Who wants to pick up some Dunkin' Donuts and watch 'Keeping Up with the Kardashians?' " the boys practiced their British accents with such brilliant prose as, "Don't be daft, we have to queue up right now if we're going to see One Direction, Guvnah!"

Check out the video above to see how it panned out and be sure to tune in to MTV tomorrow at 7:56 p.m. ET for an exclusive clip from the movie, followed by a special MTV First interview with the cast on MTV.com at 8 p.m. ET.
