Elsa Keslassy International Correspondent Playwright-turned-filmmaker Florian Zeller (“The Father”), who is at Venice with “The Son,” is joining forces with the European group Mediawan (“Call My Agent!”) and former CAA executive Federica Sainte-Rose to launch Blue Morning Pictures, a new production company. The multi-year deal will see Mediawan finance and produce with Blue Morning Pictures programming across an array of platforms. Zeller recently relocated in Los Angeles to accompany the release of “The Son” in the U.S., and promote the film during the awards season. Operating from both Paris and L.A., Zeller will now be working hand-in-hand with Sainte-Rose to develop a slate of premium films and television series.
