Elsa Keslassy International Correspondent Florian Zeller, the French filmmaker behind the Oscar-winning “The Father” and “The Son,” is set to make his TV debut with the adaptation of Stefano Massini’s play “The Lehman Trilogy.” Zeller will write, direct and co-produce the series under his newly formed Blue Morning. Lorenzo Mieli at The Apartment Pictures, a Fremantle company, and Domenico Procacci at Fandango are executive producing the series. The pair previously teamed on the acclaimed series “My Brilliant Friend” based on the Elena Ferrante novels. Massini’s epic drama charts the history of one of the global financial institutions that helped spark the 2008 recession. The original production inspired Sam Mendes to stage an English-language version of Massini’s five-hour play. Adapted by Ben Power, the production won five Tony Awards earlier this year, including prizes for Sam Mendes’ direction and for the lead performance of Simon Russell Beale.
