Leonardo DiCaprio was spotted on the New Orleans set of Django Unchained yesterday. He puffed on an electronic cigarette between takes and showed off his grown-out facial hair. He's been filming the Quentin Tarantino project since March and we've already seen pictures of Leonardo in character as Calvin Candie, alongside his costars Jamie Foxx and Christoph Waltz. Last month, Leo, Jamie, and Christoph joined leading lady Kerry Washington in Cancun for Sony's annual Spring junket to promote the movie. Production kept Leo from another important obligation though, since he was unable to attend the London premiere of Titanic 3D with Kate Winslet. He did, however, make time to play uncle to Tobey Maguire and Jennifer Meyer's daughter Ruby in NYC.
