The Teller story really begins in the summer of 2007, when, as a 20-year-old Grateful Dead fan, he was travelling home to Florida from a Deadhead festival called Gathering of the Vibes. He is in town to promote his new movie, War Dogs, directed by The Hangover’s Todd Phillips, but he has shazzy blond hair from a film he’s currently shooting with Josh Brolin and Jennifer Connelly, about firefighters tackling a wildfire that raged through Arizona in 2013. The question is: is Miles Teller the new Ryan Gosling or even the next De Niro or Pacino? Or is he, excuse the bluntness, a dick? On a Saturday afternoon in August, Teller strides into a swanky hotel suite on the 39th floor that’s just about eye level with the clouds.
