Reunited and it feels so good: That’s how we feel seeing Emma Stone and Ryan Gosling back together in this trailer for the new musical movie La La Land, set to hit theaters on December 16. (Seriously, remember their chemistry in Crazy, Stupid Love?) The film is about a jazz pianist (played by Gosling) who falls for an aspiring actress (Stone) living in LA. Romance--and plenty of sultry singing--ensues. Save the date.
