UPDATED JANUARY 08TH 2014: The campaign was photographed by Annie Leibovitz, her first collaboration with Prada.
It looks like Miuccia Prada is in love with the 27 year old actor and the new Harry Osborn (in The Amazing Spider-Man 2). The American born is returning for the brand and featured for the latest ad campaign of Prada Menswear. Congratulations! Dane Dehaan was in Prada Menswear Spring Summer 2013 campaign too. (source)
