LOS ANGELES — Netflix has secured a deal with former president Barack Obama and First Lady Michelle Obama to produce series and movies for the streaming service. The former first couple will, according to an announcement Monday from the company, potentially work on scripted and unscripted series as well as docu-series, documentary films, and features under the multiyear deal.“One of the simple joys of our time in public service was getting to meet so many fascinating people from all walks of life, and to help them share their experiences with a wider audience,” said Barack Obama.
