Iconic filmmaker Luc Besson joined Twitter this week and his first communication with his followers and the world was an announcement of his highly anticipated new movie, Valerian. The director also announced the sci-fi movie's 2017 release date and the two main actors leading the cast: Dane DeHaan and Cara Delevingne. DeHaan is set to star as the title character and his model costar will portray Laureline. This new film is based on a number of stories compiled under the series name Valérian and Laureline, created by Pierre Christin and Jean-Claude Mezieres. Jean-Claude served as visual designer on Besson's The Fifth Element, so we're in for quite the ride!
