Watch Matthew Lewis Talk American!

Matthew Lewis suits up sharp for the premiere of Harry Potter And The Deathly Hallows Part II held at Avery Fisher Hall, Lincoln Center on Monday evening (July 11) in New York City.

The 21-year-old actor, who stars as Neville Longbottom in the film franchise, took MTV‘s challenge to test his American talk.

Along with Tom Felton and Rupert Grint, the three tested the waters to just how good their American English was. JJJ has to say — Matt‘s was on par!
