Another film rumour originating from the IMDb. It’s a movie called ‘Second Coming‘, wich would be writer/director Nenad Cicin-Sain’s movie debut. Marion Cotillard would star as Galia and Mark Ruffalo as John Zener. Marion Cotillard is also listed as Executive Producer for this film.
Actor John Zener becomes an even bigger media obsession after releasing a controversial film on the Second Coming of Christ. This obsession results in the death of his wife and daughter in a paparazzi-caused accident forcing John to question for the first time the choices he has made. Teetering between delusion and sanity, John embarks on a journey through NYC, France and Spain to free himself of everything that symbolized his former life. It is through his journey that John finds transcendence and embraces the empathy that was missing in his life.
Probability: Again, I’ve found no outside sources to confirm this but the fact that Marion’s also listed as executive producer gives it more credibility.
