"With the deal, Netflix is looking to build a Narnia cinematic universe that encompasses film and TV in the vein of Star Trek and Marvel, whose franchises cross over between mediums. The idea originated with eOne and its president and chief content officer for film and TV, Gordon. Via his Mark Gordon Co, he had made a deal with the C. S. Lewis Company in 2013 for a fourth Narnia feature. Following the MGC's acquisition by eOne, it was announced in 2016 that Sony and eOne would finance and distribute the feature. Instead, Gordon and chief eOne strategy officer Peter Micelli felt there was a bigger opportunity in building a film-TV Narnia universe, got The C.S. Lewis Company on board and took the package to Netflix."
