Julia Roberts and Danny Moder aren’t the only Hollywood husband-and-wife team working on a movie together in town. Anne Hathaway and hubby Adam Shulman have been spotted on the Greenpoint set of “Song One,” which the couple’s producing with Marc Platt and Jonathan Demme of “Rachel Getting Married.” The movie — being financed by New York-based Worldview Entertainment for newcomer writer-director Kate Barker-Froyland — is about an archaeologist, played by Hathaway, who strikes up a relationship with a musician.
